Thank you very much for including an Options Menu and letting me disable Lumen etc. my PC is trash, but now I'm able to play this without too much lag. Not going to comment on any graphical Glitches, performance or weird looking Stuff tho, because thats probably from my End now.
Your Spellcrystals etc. don't follow the Hands through the Animations, only their general Position.
Music is nice, menu button for closing on the Top is weird.
Didn't know what the Room Colors ment initially, overall the UI Stuff could be better.
As could the Rooms and the Weapon Animations. They are just kind of nonexistent, and in the case of the Sword, the Rocketlauncher flings weirdly across the Screen. Shield is useless, does nothing.
Rooms are all okay-ish, but rather bland, and all end up in just circling around the outside while shooting behind you until everything is dead.
The Skull-spawners also lag out everything extremely, might be relevant even with my trash Setup, so I thought I'd mention that.
Overall Gameloop works fine I guess.
