Such a cool game! I love the way the lighting shows the different colour obstacles! The art is perfect and fits in with the theme nicely. It almost feels like it could be a finished game so well done!
The only improvements I could think of for this are that the music can get a bit repetitive so maybe an option to turn it off would be good, and adding checkpoints too because it is so annoying having to start it all again when you die hahaha.
Apart from that it is a solid game, keep it up!
