Hi, I've made a video about the demo and wanted to share some feedback about it ^^, hopefully it is useful for the development :D
-The gameplay mechanics are fun AF, the gameplay loop always feels fresh and quite polished for it's development state. In this regard just keep working in this direction since it works quite awesome.
-Visuals on the game are quite NOICE, really fit the theme of the game and work well under "massive waves of enemies" circunstances without turning into a mess when the screen gets full of enemies.
In conclusion, the idea is great and I hope you keep working on it. Hopefully this is useful for the development :D, also if you could subscribe that would help me a lot :)
