Very well made combination of 2d puzzle platformer. If I were you I wouldn't have thought of shooting myself with the gravity gun xD Unfortunately I got stuck (not as a bug but my brain is too small to figure out the puzzle).
Yeah, that's a good idea, I've seen people do this in other jams. Maybe I'm too slow, but in one other jam I had the same problem, the developer had video about his game though. Yep, good idea.
