The sound design, visuals, and general feel of the game are great. The mechanic is pretty interesting and I only wish there were more challenging levels to test the player's mastery of it but it's a game jam so of course it's gonna be short :)
Some people are pointing out that the movement feels a bit floaty but I think it makes it much easier to get a grasp of the main teleportation mechanic. Perhaps you could improve the theming to give context for the floaty gravity. Maybe it takes place in outer space or the character is some sort of balloon-like creature?
Overall, I really enjoyed this one!
