Totally agree, the ending has no much sense, but I didnt find time to do something better before the submission :D Now is including some more levels, mechanics and a simple (but better) ending.
I'm glad you had fun and clear all the levels. I'll be fixing the music in the future to be really synchronized with the gameplay, so I think it would make easier to stay in rhythm.
Thank you very much Rieux, I really appreciate your comment! <3
