Fun concept with excellent visuals. It reminds me of the flash games I played as a child(in the best possible way). Good bones here for expansion.
I do think it needs more player interaction because as of right now the player only launches and then the rest is up to luck. Its still super satisfying to go far but having more agency in the plane after could improve the experience. (Perhaps pickups, or a finite number of boosts, or an upgrade system.) Obviously this is a game jam, so you couldn't get to those things so they are more like suggestions for an expanded version rather than critiques.(which I would like). I think you guys focused on a lot of the right things and I keep coming back to retry for a higher score. Its a super chill game with a strong set of bones. (it really does get exciting to see if you are going to get further or if you are about to hit the ground hard.)
Great Work
