Nice game, runs well even with what looks like thousands of enemies on screen which is nice, the spiral mechanic is neat but I think could be fleshed out more, there's some depth to that system (Reminds me of noita wands) but in this demo its not really that important the order you do stuff. I like it in theory though.
Fun game, I never played vampire survivors but seems like you've implemented their winning formula pretty well, nice work!
