This is super super fun! I tried to make a vampire-survivor-like game with my siblings for my second game jam (Survivors) and it wasn't very fun at all so its very cool seeing one that is. It isn't easy bringing all the elements of a game together into an engaging product but you totally did it and that takes skill and/or talent. The only things that could use a little work are the art and the sound effects, I think both work okay here and communicate everything they need to but if you found a way to polish those I think you could have a cult-classic on your hands, very very good job. If you choose to keep working on it, different weapons would be really cool.
