Oh wow, I really really enjoyed the game. The idea is straightforward, but it works so well that I fell in love with the game! XD
I really like the idea of building your own deck, the roguelike setting works super well with the game.
I am just a little confused at the end, since the whole game was letting you take your time, and the final boss suddenly makes you think on a timer (I got punished for going below zero, but I feel like the boss didn't explain that mechanic)
I will definitely play it again to win for real!
