I am relatively new to picross games, but I enjoyed it a lot! :D
Some ideas/opinions:
-You should probably add an options menu to let the player disable completely the wobbly/colored text.
-I couldn't use the buff because the game finished too soon XD Does it affect the smallCure too? By the description it seemed it woould only change the attack.
-This needs music. I'm glad you are planning to add it :)
Please continue with your good work! :D I would love buying this game on Steam (you could probably release it on early acces).
