Fun, but misses an aspect of what made Vampire survivors so fun, attack variety is important in these kinds of games, especially since it incentivises finding weapons that work together, but it's fully understandable that, when under a tight time limit like this, it's not considered.
While the animation work for the reaper player character looks spectacular, the broken animation calls ruin it slightly, and it sticks out compared to the static enemies just sliding around, I'd have preferred if half the frames of animation given to the player were given to the enemies to stop it from looking so jarring
But, the abilities are fun, an interesting idea to add activated abilities to a Vamp Survivors style game, kudos to you, that's a fun idea
