Took me about 20 minutes(I had no experience in running pygame), but I finally got the game to run! It's a really nice little game, and I especially liked the visuals!
The gameplay is lacking a little bit of complexity--in my gameplay I usually just spammed/held the buttons. It could be interesting to add a stamina system to limit gameplays like mine(Tbh it's kind of cheating/cutting edge from my side). However, the visuals and audio are quite well done. Nicely polished.
Great job!
(Also a little sidenote: In the section saying which operating system the file is executable for, check the windows box aswell! I used windows to do the same downloading process, and it worked!)
