This entry feels too barebones and I don't see how it links to the jam theme.
Some improvement suggestions:
- The jam's theme is about running out of time. You could add a countdown timer that adds seconds every time you pick up a coin. If the timer hits zero it's game over.
- The game's difficulty is very easy. Definitely needs a difficulty adjustment as time passes.
- Jumping was never needed as there was always a lane open to just run through. You may need to consider redesigning your spawn logic to force the player to use all their moves.
- Set the audio volume to a more reasonable level and include volume controls.
