definitely my favorite so far! it's a clever concept executed well. it was really satisfying to build up a ton of speed on the last level. it's small but it feels complete. it has a nice litttle vibe to it too!
i got confused in the first room where you get the green - i thought you only get to use it once, so i actually made my way all the way to the end without changing from green. maybe in that first room it might make sense to show the space-bar prompt until they press it twice, to make sure they know :) other than that it was pretty much perfect!
