Really nice puzzle game! The puzzles were not easy and gave me a good challenge, due to lack of time I was not able to beat it but I think I'll give it a try at a later date. I also liked the art that was cute and functional. Good job!
A little suggestion for QOL, it would've been nice to have a button to just reset the level instead of having to finish the energy, but I understand that when the timeline comes closer and closer it's not one of the first things you think about :D
