Very nice! Small but well put together! The art is nice and the audio provided by the jam works great with this little project! A couple of notes:
- The jump is much to fast, leaving the player needing to be scarily close to the cacti. Would be better to implement a slower jump and have it stop jumping once you release. This would give the player more control and if they mess up it's on them and not the jump mechanic.
- Wish there was more! I think you could have a lot of different obstacles with a desert scene.
Overall good work! Very well put together little project. :D
