Oh wow that's polished! Idle animation, voicing, many types of assets... The level of detail is absolutely insane for a 7 days game jam! The game is beautiful, and I love the sound design.
The gameplay is also pretty good! I've found that you can walljump if you "flip" against a wall, and I played quite a lot with that mechanic =p. But I enjoyed the mechanics, it was simple but fun enough to make me stay until the end, great job ^^
The level 4 seems to be bugged? The game crashes when I open the third door, and pressing 4 also crashes the game ^^'.
Overall a nice submission, congratulations =)
