Wow, our games share lots of similarities but there are some things I think you did better than I did. For instance, I really like the upgrade system. That's something I wish I got around to making in my own game. I like how you also made it fun to just summon the monsters. I thought I had to make it part bullet-hell with your evil mastermind on the field too to make a reverse Vampire Survivors fun but you made it work. Good job!
