it took me a minute to get my bearings but the description was helpful.  very creative new mechanic I haven't seen before.  Kudos for that!  The diagonal move was a bit tough and that blade level was quite hard but I thought this was a pretty cool experience well done!!

I really like the idea for the main mechanic in this game (as well as the pun in the title) The difficulty in the blade level is kinda insane (though I should add, that I’m just not that good at this type of games) (Not important, but I LOVE that the Begin button scales with every drop of blood!!)

Very cool concept for this game! I think with a bit more polish (in terms of explaining the rules mostly) you have something here that's pretty unique and quite a headscratcher. Maybe the timing was a little harsh?
I must also say i was not a fan of the big red screens used for transitionings, they were very trippy, especially alongside the music :P 

-[EDIT]-

After your instructions, I played again. And i think the game has a cool concept. But it lacks the initial instructions. This can be turned into a great indie if u focus on it’s core loop / iterate it’s core loop more. I think the mistake u did was throwing player with all instructions (ex[ecting them to read). But trust me (from my past experiences, both as a developer AND as an gamer), You have to find a balance between tutorials and game (you could watch mark’s video about “Valve’s secret tutorial”. Where they let player have the control of whoom they are controling “whilst” teaching player what they can do.

For example, instead of what u did in “Door” level, u could intoduce player about your game bit by bit (“like showing them how they can attack, how not to attack, etc), before jumping them to “Actual” intended gameplay.

I was struggling a bit with this game but I did stream it! And started to get a hang of it! 
Good Job!!!

It was hard to evade attacks and calculate the sequences.

I was stuck on level 2, but I like your game concept.

Jesus this game is difficult! But I think it's a cool concept and it's easy to play

Hey, just played your game, but didn’t understood what to do, can u explain it in short (i will rate, after i can play your game successfully)

Nice game !

I personally think putting all the text in the door level that has a timer is not a great idea, if you want people to read the controls dont put a timer of 10 seconds to beat the level (altough you just lose 1 life and you are full life in the next level, the player doesnt know it). I chose the door level 3 times in a row in order to read all the text. I suggest entering door level (with no timer), showing only the first 2 lines of the text and putting press space to continue, then 2 lines more of text and space to continue, another time (shows all the text) and then press space to begin and tjhe timer starts and you can play. (next time you choose the door level this tutorial wont appear, it will appear as it is currently on the game) Another thing is that blade is "impossible" to beat, my best battle left him with 7 hp, but the game is about finding 1s and searching if they have a 2 next to it, then a 3 etc, that is difficult cause in most cases in the whole screen there are like 8 ones, but only three o them have a 2 next to it, and if blades change them you cant do damage in the whole level. I suggest making maps so you can start with bigger numbers (now its always 21 or 321, i almost did a 54321 but a blade changed it) and i would made blades appear less often so the game feels possible to win.

The art is nice, the music is nice, its a short fun experience, i hope you continue developing it and polish so its not that hard.

Also, you can try my game if you want, it just takes 5 minutes ;)

This is really cool! Love the idea of a puzzle where your movement does damage and the enemies change the map. Nice job!

I like this game for its originality, and it gets my mind to recognize shifting patterns, which is suspenseful yet rewarding.  The art and increasing levels of difficulty make it even more fun as you go along. The music and color scheme create both a sense of impending doom and ironically optimism at having some control over the outcome.  

I'd play this game anytime, no matter the mood because of it's aforementioned qualities. 

Dodging the blades while trying to solve the puzzle was pretty hard, but fun! I also liked how the Begin button kept getting bigger. That was a cool idea. Great job!

Wow that was hard! This kind of plays like a word search but under an immense amount of pressure. I did find at times it was difficult to find a stream of numbers leading down to 1 that wasn't just 3-2-1 or 2-1, but a very interesting concept that I could definitely see expanded upon. This also could've benefited greatly from some more detailed instructions or a tutorial, but I understand that time was limited! Just took me a few minutes to understand what was going on. This was definitely unique, and I enjoyed playing!
