The game's pretty fun, but there are a lot of glitches and every run ends up feeling almost entirely the same. The final boss is an insane power spike and incredibly frustrating to fight against - unless your build only has like 5 cards, you can die by getting bad RNG 2 or 3 times in a row, even while having a decent build (I had a 120dmg card and 140 health and still died because the boss dealt 40dmg to me 3 times in a row without the 120dmg card appearing)

Well, the last boss dies almost immediately if you have the skill that makes kicks out of unspent energy during the exploration phase. It takes away its ability to evolve. Only way I've ever beaten the thing =)
Edit: Well, speak of the devil. Got a perfect snowballing combo going where a free card would do damage and then draw itself infinitely. The final boss has fallen!
