Nice work on this one - I think the story is interesting, and I especially like how you managed to get each character to feel separate, even though I think it may be to their detriment in FWMC's case.
I think the gravity reduction on them might be a bit too high, especially noticeable on level 4 where you need to make nearly every jump perfect and chain bomb jumps, otherwise you can't reach the top. Barely managed to make it to the exit after I ran out of bombs on the last jump, and happened to have enough time to wait for a car to come by that I could parkour off of to get to the pebble in time.
But I do think this is a solid submission for the jam, and outside of character balance it's really well polished! Would be cool to see some more content added after the jam, if you feel up to it. Good work!
