I found myself playing this game for quite some time, I really like this kind of games ! A music based vampire survivor like ? Sign me in ! It was kinda hard though, I found myself with like 50 enemies surrounding me after 40 seconds of game time once.
Also had a lot of fun messing around with the different upgrades. Launching 6 disco balls at the same time destroyed my ears a bit but it was really fun. One of my favorites so far !
I noticed just a little thing. I think the main attacks (lmb) AudioStreamPlayer must be an AudioStreamPlayer2D placed in the center of the map. Because when you go out to the sides, you don't ear their sound anymore haha.
