The collision sounds are a bit annoying at times, and i experienced a crash in the level with spikes but the game has auto save so i didn't really lose any progress, and the README file is also quite a nice touch, it's not just a file that exists for no reason, you really have to interact with it which makes it even better.
Overall enjoyed the game, it's a bit short, but i enjoyed every bit of it.
Now if you'll excuse me, i'll go and try to get a higher score this time! (My first score is 82 btw)
