Really cool idea, and well executed! I was really impressed with how well my crappy doodles registered. I love vampire survivors so this felt like a really nice twist on it :D
I wish there was a scoring/high score system so I could compare each run and see how I did, I also wish there was some feedback when killing enemies so it felt a bit more satisfying to get a big hit.
Loved the silly SFX, it made it super funny, and appreciated that you had time to include music as well!
