Hey skymanvn, I checked out your game on stream, you can check the recording here: 

While I really like your concept, I was not able to get into the game and enjoy it longer, the 8 bits short loop music really hurts my attention, and the tutorial felt like a few steps were skipped, it's more of a hassle but its important to break up the tutorials into introductory beginning stages, I was pressing around to see what key would change what, there are much to be desired for the tutorial, otherwise the core game seems solid. Keep going with polishing this one. 

This was a really cool spin on the falling block puzzle genre. The tutorial had me a little confused at first, and it took me until after to realize that all I really needed to do was form math equations with the block lines. But once I got that down the game became a lot of fun. Having to balance between setting up lines for attack and defense was also a nice touch.

My only complaint is that at one point my lines got pretty high up, almost to the cutoff line for defense. And as I was trying to clear a horizontal line that high, it instead kept clearing vertical ones. I guess the game prioritizes clearing vertical lines over horizontal, but that can sometimes lead to you being stuck in a loop where you can't get an attack going.

Otherwise it's a really cool game, I'd love to play the finished version when that comes out. 

1. Very fun concept! This is very experimental and I love that. I missed the tutorial (that's on me, I do see the giant glowing text), went back to it, and beat the game.
2. When doing defense vertical clears, only the vertical that clears have their gloops drop. This created many runs where I bricked my board, unable to do horizontal clears and just stuck until I overflowed the board. I think everything should just drop like Tetris, more instances of combo clears is probably more fun since those are the highlight moments. I understand the intent that vertical clears drop vertical and horizontal clears drop horizontals but I am not sure that is worth it.
3. It seems like the game just takes the first number when reading the equations on clears,  I wish it took the biggest number before an operation. Although this might work against "-" and "/" operations. 
4. Placing big numbers in a vertical or horizontal together should intuitively be a good thing but not in this system.  Maybe something can be changed about that? This point does not feel as important, just something I had to figure out. 
5. Overflow happens instantly, maybe some lag between gloops touching and placing.
6. I almost never looked at the shape deck or block deck UI, might just be me, but I was constantly staring at the UI  under the enemy. 2/5 of the screen was UI I never looked at and that 1/5 under the enemy was all I stared at. I think it is just too much info in too short of a window for players to digest, a coming up next UI might be better. From my playthrough the UI I was searching for the most was Turns Until Attack > Enemy Block/Enemy Block Cooldown > Enemy Attack Value > Enemy Health > My Health (probably cuz there's no heal and it is what it is. I can't do anything about it).
7. Really like the gloop (the color and shape made them very distinguishable).
8. I really like the enemy designs.
9. The attack/shield animations are really nice. 

Hi skymanvn! I really enjoy these block falling games and seeing one with a roguelike twist was really fun!

Started in the tutorial, just a couple of little notes

• The first move you are getting the player to do is drop a 2 piece item into a 1 piece slot, but don't tutoralize the rotation so it felt to me like I was doing something wrong and had to exit out of the game screen to see the controls because intuitively I wanted to press R for rotate, which pulled me out of the experience (specifically on your main menu screen controls: players unfortunately don't read a lot of the time and I am totally guilty of this)
• Your tutorial has a lot of text after the 1st move, so much so that I forgot half of what it was saying, you may want to split things up a little bit because there is A LOT of information to take in with the math equations
• Unfortunately I came out of the tutorial really not understanding the game outside of fill things horizontally to attack, fill things vertically to defend, how things were calculated was totally lost on me

For the game itself

• The items not falling after being cleared really threw me off, but that's probably more of a me problem then the game itself so take this point with a grain of salt
• With everything that was going on I started to totally ignore the values on the blocks themselves and just started to place things down to create lines vs actually thinking about what was going in those lines. I'm not sure how you would reduce cognitive load on a new player around this, but it is a lot
• And sort of playing on these 2 above points I really just found myself reacting defensively to what was falling down sorta like "Ah! I just need this to go somewhere, wherever so I can clear out at least something so my board isn't totally scuffed"

I know I've been a little negative and I'm sorry, but I really do think that this is such a fun and interesting idea and the block falling section plays super well and smoothly and I had 0 issues with it at all. I just feel like there's either a couple of things that could be simplified OR some more gradual onboarding into the complexity is needed (Slay the Spire's slow mechanic introduction by not giving you all of more complex the cards until you level up a bit by playing the game is a good example of what I am talking about here). I hope you continue on with development would love to see what it becomes when you are done!

This was really fun! A nice refreshing twist on the line clearing block stacker.  Some general comments:

1. It would be good to introduce the controls to the player during the tutorial.  I was able to guess the correct controls coming in using prior experience, but any game could be someone's first game.
2. it's not immediately clear how repeating blocks will behave (ie. more than one operator or number in a row)
3. It's not tutorialized that equations resolve left to right for attacks and also top to bottom for defense
4. It would have been nice to know that creating a negative value hurts the player instead
5. The defense line muting out any tall stacks is a little confusing.  It initially seems pretty punishing, especially since it's an unknown mechanic.  It might be enough to know about it in the tutorial.
6. It's not too clear when a block falls to the bottom or if it just drops one line after a clear. (seems verticals drop all the way down? and horixontals only drop one line?)
7. the randomness of the next block feels like it takes a little of the player's agency.  The complexity of anticipating the next block (or possible blocks) is like trying to play two simultaneous games of blackjack.  Rather than trying to orchestrate combos I felt like I was simply reacting to the next block without planning anything.  There is a good cognitive harmony with the combat for it, but the player will be missing out on dopamine hits from high skill line resolutions.

what a fun and addicting take on a classic!!! i love this and really enjoyed my time playing. besides the game mechanics, the art is also looking polished and i love the character designs. the only out of place thing that happened is that i was in the middle of the battle against the bat and the music stopped looping. overall, a very promissing game, congrats!

I love it, it's really fun! I don't understand at all how making the lines and the equations work, but even with that, I had fun.
Like, I made a line and I thought the number next to the plus or minus made the equation, but it took other numbers instead.
I couldn't tell when it was a shield or when it was damage.
I didn't pay attention to the deck, I didn't notice that is there until I read what feedback you were looking for.
I mostly just cleared lines, tried not to lose, and beat a few bosses.

The art is amazing! Maybe adding a background or even a simple parallax could make it even better. As for the rest, I love the slime, the bosses, and the UI.

This is a really good game!
