Really neat game! reminds me of Vampire survivor, but that's such a solid foundation that you can build however you want, so smart choice.
I had lots of fun messing about getting projectile size big haha.
I will say that the web builds UI doesn't scale very well in full screen. The HP bar is tiny, and when fading to black it doesn't cover the who screen. On unitys canvas their is a drop down for scaling UI, imo its always a good option to be on scale with screen size for web games / most jam games.
But that's a minor thing. IMO this game was really fun and you did super well!
Fantastic work!
