A new (at least to me) kind of puzzle game where you need to fill in the blanks with your worm-like character. You instantly move across the direction you press like a sliding block on ice puzzle, but you are the block and you leave a trail that you can't double back over. I can't beat level 1-5, but it is possible to play all levels out of order in case you get stuck on one level. I think this concept could be expanded into a bigger game. Just add some story beats at the start and end of each group of levels.
