A rather ambitious project for a game jam, movement like this usually requires lots of playtesting and polishing. Unfortunately it does feel unpolished in that regard, I quit the game after a while after the timer had ended after not getting far. The timer also seemingly didn't result in anything, unless I would have needed to complete the level to see the effect.
Not much to say about the rest of the game, a basic artstyle and some looping music to set the mood are ok for a jam game.
I did check the "comic", which was a nice addition, but I think it would have been better in the game itself. At least it shouldn't be expected to view content outside of the game for context.
