Like the games and the combination you can do!
Sometime the combination didn't work and I'm not 100% sure why, deleting and rebuilding fixed it tho.
It does feel like a tutorial or more slow levels first would be good, always having to open the hint and trying to make sense of everything was a little hard at first.
The music could put set on a Singleton so it doesn't reset every level, and the UI could be reworked a little bit, but other then that, the puzzles made me think about the layout I wanted and how to achieve the best result.
Cool game!
