A really solid platformer, the shooting mechanic worked well and movement was tight. I liked the transitions between levels I appreciate the multiple enemy types. It seems you're aware of the issue of getting stuck on corners, I think this would have been a lot less defeating if R reset the level rather than the entire game.
The cover image seems like it was taken on a phone, I think a screenshot would have worked better. Overall an enjoyable platforming game with a unique mechanic that sets it apart, nicely done!
