a very well polished bullet heaven! the immediate highlight of this game to me is the game feel; the visual effects and art for firing and tearing through foes are reeeeaaaaaally good and extremely engaging! i especially enjoyed the spectral daggers attack. the diversity in attacks was very cool, and they all felt quite polished individually. using cards as bonus spells was a cool spin on the formula, although i noted that the use of MP felt quite pointless as the cards' long cooldown typically meant that you'd already regenerated all your MP by the time they were ready again.
my main criticism is that the balancing could use some work, as it feels like the early game can be too punishing, but then very quickly becomes too easy once you get the right cards. however, i appreciate that this is difficult to do well in a time-limited jam environment where you can't test as thoroughly.
it also seemed like there was no audio, despite there being audio settings? given how good the polish is already, i'm sure even just a little bit of sfx would really take it to the top.
overall, i'm very impressed with this game, and it's extremely fun. incredible job!
