I see what you meant when we talked last weekend. That bug makes the game significantly harder.
Regarding the game... It definitely was a pretty ambitious idea. Personally, I wouldn't have dared to attempt a rogue-lite deckbuilder for a 48h jam, haha. So considering that, what you managed to achieve in such a short time-span is remarkable.
Balance is kinda wack, but that's to be expected given the timeframe. And UI could really use some work in order to make the game's initial barrier to entry lower. As right now it is kinda intimidating at the beginning, until you finally figure out what's what.
Despite all that, the idea was pretty creative overall! Not a bad entry into this year's jam.
