This game has a really cool idea and its fun to play but as you said in the description its very hard. If it ever got updated i would reccomend something like an index for what everything do to make deciding what to level up easier (in my playthrough i figured out the workings of almost all the ones in the third row and of the ice element but nothing else). An other thing i would reccomend is having the player attack every 2 enemy attacks cause the moment you get a 3/4 enemy room its usually a death sentence. Other than that the game is very creative and fun, the music fits very well and the art even if simple is charming :D
