Pretty cool, however, like others have said, you need some more enemies, however, the art style is MWAH,brilliant. You also need to add a title screen next time, just helps as a nice introduction and helps with polish(but your polish is really good for your first game). Finally, you need to work on scaling and player interaction, after a while, it felt very repetitive because the enemies were just a few, and I had already raised my passive attack(mke it less op) to a very high score, try to limit the timer next time cuz it was a bit of a bore though.

Very solid for your first game! It clearly was the clicker starter.  One small improvement I would make is that game gets too easy after a few upgrades and you sit watching until wave 5. But very nice work. Congratulations 🎉 

Game was a cool, fun spin on vampire survivors.  I'd consider adding a few different enemies, and maybe different power ups, but other than that it was fun. I to made a vampire survivor, Cleanup Crew, feel free to rate it if you have the time!
