Love this. I want to start of by saying the player movement is great. It's not perfect, but it wasn't too slow or too fast and gravity feels about right. The music choice is quite fitting for this style of game too. I would also like to say great job on your lava shader. I have one in my game but your one looks a lot better than mine. But overall your game was pretty fun and I enjoyed this.
Something I noticed was, the player looks like they gain points by jumping and not by landing on a platform so I can spam the jump button multiple times on the same platform and gain a couple of points without moving.
Also, a great addition you could add is a high score system. This would encourage the player to carry on playing so they can beat there personal high score.
Great Job.
