I really enjoyed this! I wanted to feature it in one of my Toast Bites indie game lists, but I like to use the music from inside the games themselves as the background for their spot and none of your tracks could be played fully without interference.
I'll keep an eye out for when you release it in full and feature it in a list then. Especially with the music being the focus, I want to make sure it's highlighted.
As far as the demo itself goes, the only technical issue I had was in the level where you grab the cubes that each make a sound. The game kept crashing on that one for some reason. Other than that, it was great! Best of luck with the album and all of your other work!
