I love the overall atmosphere of this game, visuals and audio-wise. The chaotic particle effects, the really pretty customized UI, the way the screen shakes and how all the stuff is all over the screen, it's awesome.
That the platforming is a bit difficult to play, though. Since the platforms are always falling as you stand on them and your shots can't go through platforms, I often found myself being walled from going any higher due to not being able to shoot enemies or platforms falling too low.
That being said, I would love to see where this game goes and where you go as a creator from here. Great stuff!
