Ok, so first of all the sad part. I haven't seen a final screen after my first playthrough. It was just black. But on the bright side, i had to play your game again!
Honestly, this game is too good for a game jam. It just works. Graphics and gameplay and everything. I was real cautious, but then i died and realized that game doesn't reset, which is a good call for a story driven game. Double jump helps too, saving you from spikes and other dangers. I'll be honest, at first i thought that ability was flatulance based. Until i got infinite jet pack. My bad.
All of that, best boss battle in the history of videogames, and soundtrack still manages to steal the show. So yeah, excuse me, i'm gonna go spam the link to everyone i know.
