"So that sucks." Now that's a great conclusion message.
The game is super fun. It looks and sounds pretty good. It's very pleasant to control, the pool of cards is good too with some different effects and managing the distances and ranges is fun, I like that you went with this tactical positioning instead of a combat layer separated from exploration, especially with distances being very important to most cards and some cards directly playing with these distances. I like that you go through your deck only once for each level, that's a cool twist on the usual fare and I can imagine this last part being very interesting in a bigger game as you might want, for example, melee cards with high damage rather than ranged ones with less damage, with the caveats that there's melee cards of course, these could be fun decisions.
The game is very cool, thanks for sharing.
