Fun game! I loved the concept, very retro arcade-y/bullet hell,. Personally I found it a bit too hard and the lack of any checkpoints (or at least ones that I reach) made it a bit frustrating. I think this is partially due to the control. This is mainly a skill issue but I would have appreciated a skill slider adjusting spawn rates or health amounts. The art and music were great, felt perfect for the game and it ran very smoothly!
Overall great game, Well done!
