I really love your game! First off you had me super happy right at the beginning cuz I could map my own controls. Then I got into the game and had a blast playing.  I really think this is a concept you could expand out into a full game. I think one small thing id like to see is different colored barriers. once the frequency of barriers went up it got hard to tell which kind is coming first. I think maybe if u alternate between two different colors it could help with this confusion.  But overall i gotta say well done! Had a lot of fun and really appreciated how responsive the controls are. If you expand this game please send me a message or post it in the jam discord. I'd love to play and test future iterations for you. 

I think that the concept is really nice. Simple, fun, and well-made especially for the time constraint. I think the difficulty ramps up really quickly, though.
