I am playing on the Linux download. I started playing on v0.1.16.1, and later, after it had been released went to v0.1.16.3. I see that 1.16.4 has been released, but have not played it.
I like the animations on some of the cards, like Yarn Ball, and Pin Storm.
The second combat is a bit tough in my opinion, removing the 12 attack ability would help.
When I merged two cards together, I did not get any animation, all I got was a black screen that I needed to click through. I got the same thing on both versions.
I got the "make a deal" event, and I chose the trade numbers option, but I only had one card that fit the criteria (I went with the yellow one), I could not confirm, but I could go through the rest of the dialog. When I left the event the buttons for show and confirm were still there. The buffed card was the same as before the event. On the new version I did test on a card that I had multiple of (I went with red, +/-4) and it did work, I was able to buff my card and de-buff a different one.
When I had Entangled applied to me and two of my block cards were entangled, when I tried to use a non entangled block card, it applied to the back-most enemy.
After every other event, the info at the bottom right of the map would disappear.
I feel like after you beat the boss you should learn more about who you are and what happened that resulted in you being in the attic.
One of my favorite cards/card combinations was "Body Slam", and being merged with “Block”, in a way so that block goes first, resulting in more damage from the attack. I also really liked combining "Yarn Ball", with the effect "Mirroring", resulting in giving an enemy two stacks of the yarn ball effect.
I really liked the artist random event, though it did not seem very common, so I did not get to use it much. With the new version I would almost certainly swap out my weak block for something else.
I like the concept of rejuvenation, although each of the times I have tried it, I have gotten a 20% rejuvenation, and only gain one, or less HP with my attack, and that did not feel very useful.
I am not sure if multiple stacks of the yarn ball effect is working properly, it seemed like on the next turn, the enemy's attack would be less than normal, but not reduced by half, closer to three-quarters. An example I have of this, is on one of the fight with the Natelie/Ant enemy, I gave them multiple stacks of this effect, and on the second turn of it, they were going to do 9 damage.
I feel like rest spots should heal a little more then 20 HP, maybe closer to 30.
I like your random events so far, although there are not a lot of places where you can get them.
I feel like the map should be a bit bigger.
I feel like the final boss is a bit weak, the two biggest things that make them annoying is stealing your gold, and having high health. Perhaps adding more to either the boss itself, or giving them allies who have their own special challenges about them could help. Possibly have the boss have an ability to spawn enemies when they are the last enemy on the battlefield.
It might be cool if after beating the game, you had a New Game + mode that allows you to go back through map, with all of your cards and upgrades, maybe starting at the third king event, and allows you to take a different path to the boss. Maybe also give the boss a boost to their attack and health if you continue after beating them, just to make them feel like a bit more of a challenge then they would if they stayed the same.
I like the theming around crochet. A Wandering Songbird already gave you some good advice on this topic, and I do not have anything to add to it.
If you click cancel on the card merging screen, you can re-choose your reward. The options are: Add a button, Skill Bind, and Attack Bind.
On the new version, when I get the game over screen, it does not take me back to the main menu, I needed to pull up the pause menu to go to the main menu.
I feel like, in general, the combat is a little too difficult, as, in almost every combat, I take some damage, because I did not get enough block cards, and since I found rejuvenation gives me 1 or less health, I almost never get the health back. Even when I go to a rest spot, I gain some, but then unless it is the final boss, almost immediately lose most of the gained health. This could be what you are going for, but, these are my opinions.
I like your game so far, and enjoyed playing it.
