This is quite a challenging game. Got that jump king vibe, and it plays quite nicely. I also like that reward with the coins, and it rewards players going out of their way to collect them. I also like the checkpoint system you've added to the game and it certainly eases the frustration quite a bit. I do hope the game has a bit more graphics that were not the default unity block and capsules, but you would probably need a 3D artist for that. I also think the jumps and timings were insanely tight during the latter half of the game, especially the part with the snakes.
Anyway, I still think this is quite a nice game. Keep up the good work!
