A very interesting concept. Unfortunately, there just wasn't much for me to get into with it. I really liked the artwork, and I can see a lot of the time went to that. One suggestion I'd make is with the arrows telling you what direction to go. Instead of having both left and right be on the bottom-left, how about putting one on each side, so it points right from the right and left from the left. I'd also highlight the goal once it goes on screen by removing both of those arrows and pointing to it directly.
I see in the description that this was your first game jam, so congratulations on completing it. Running out of time is a really common issue with jams, and the most important skill to learn and develop with them (IMO) is time management and keeping the scope of your game within what you can do in the limited time. I made the mistake of going with a really high-concept game my first game jam (before doing the GMTK jams), so I've been there myself. Just keep practicing and participating in jams, and it will get easier with time. Good luck with your future game jams.
