Solid enough concept for a game: Get past tricky obstacles to get to the goal, with different patterns to deal with.
My main issues with the game are that the visual design is a little too busy and monotonous with the squares, especially with how they are spinning both in the level select and in the levels themselves. I understand that there is a theme you're aiming for, but less is more.
The other thing is that the difficulty curve is a bit too steep in the beginning. A slightly gentler slope in the beginning would do well to allow a more players to ease players in, then hit them with the more bullet-hell levels, which this game is clearly all about. Maybe a more linear path for the first few levels in the beginning, and then give them options to choose their own paths to hell?
A little tweaking with the visual design and progression structure will make this a fun and challenging game. Good luck!
