The slippery movement seems to be a common feedback. I wanted to try something different from genre conventions, but it ended up backfiring. Not every risk is a good one!
I'm glad you like the presentation, and I hope you still had fun! :)
Its true. I think there is something to that. The bullet patters are very tight typical of a bullet hell like this one. Maybe if you had patterns that went more with your movement you could do what your trying to. Just thinking on it. Very good looking game!
