There have been a lot of awesome games this jam, but I think this is my favorite so far.
You have a lot to be proud of here! Color swapping was a big running theme but I think automating the process makes it much more interesting, and having the chameleon glow is a perfect way to telegraph it. The audiovisual presentation is great too, kind of reminds me of the golden era of Flash games.
I also appreciate the level design. There are only 5 but each one challenges the player in a unique way and you got the difficulty just right. The colors are also swapped quickly enough that I never feel like I'm just standing and waiting around for things to change. Excellent job.
