i personally love this game. I finished Nirvana in about 30 mins but, it was 30 mins of fun. I hope the devs can extend this game more and have more maps, bosses etc. For me personally, It takes a lot for me to really like a game and this game did it for me.

kudos to the devs

Awesome core gameplay, now go and make full fledged magicial bullet hell FPS!

Sweet and short, very fun moving around and the combat is nice (tho I wish I'd take more dmg).
Only issue I had was with volume controls, all 4 sliders are treated as the volume slider for everything, the last one you touch is what the volume setting will be, and lastly while the slider goes from 100 to 0 the volume stays at 100% until you take the slider under 1 to 0.9/0.5/0.2 (only 3 options I had under 1).
