Ay pretty slick according to me. Made it through with 3 collisions.
I suggest you establish player goals at the beginning of the game, and then check whether they did what they were supposed to do at the end.
- A simple "Reach the checkpoint!" may be super cliche, but goes a long way in giving the player something to want to do.
- Then put a checkpoint at the end. Once we reach, give us a win screen - suddenly its not a mechanic, but it's a complete game. The player overcame an obstacle and was rewarded with victory.
Totally cliche example, but highlights the fundamentals of a gaming experience.
Good hustle overall - all the best for future jams!
