The game was alright in my opinion. To improve it I would suggest adding a fog so you don't see the obstacles until you come near them, secondly, I would suggest for you change the skybox to a solid colour. Finally, I would suggest that you make the player automatically move. This is just some constructive feedback I wanted to give you. I've made my own version of this game a couple of years ago, you can check it out and use it to come up with some ideas but I'd appreciate it if you don't copy it exactly
