You took the concept of a game like VVVVVV and then managed to put an original spin on it that is totally in line with the theme. As you might be able to see if you look at my comment history, I usually have some constructive criticism, even for games that I really liked. But for this game, I have nothing. It's really good. Perfect score.
I found this game by searching for the Metroidvania tag and looking at ones from the GMTK game jam. I found some great games this way, but alas, yours was the last one and now I'm out of my Metroidvania fix. At least I saved one of the best for last!
