Thanks for playing! Glad to hear you liked it! This was my first 3D game and I have to say, Godot made it fairly painless... It could do with a bit more polish but for a weeks worth of development time I'm quite pleased with it! To address your points:
1. The inertia was intentional, as it allows you to coast for a bit to collect another fuel can. That being said I will add a timeout to the game that basically only allows you to coast for a short while before failing the shift.
2. Yes I agree that can be a bit annoying - but I tried to mitigate that frustration by allowing the player to change camera angles with Q
I totally intend to do some more work on the game after the jam so will take your points on board!
