This can definitely be an addicting game, but there are a few bugs that need to be worked on first.
1. I ran off screen and wasn't able to come back.
2. Moving too far to the left or right slows the squirrel down. I wasn't completely sure if this was an intentional game mechanic or not.
3. Some acorns seemed to have a wider hit-box then is shown.
Other than those things, this is a pretty good first-time submission. For future projects consider things like: advancing difficulty, points, music, and maybe levels to break up the monotony. Good luck on future endeavors!
