This was for the most part solid and well-scoped for the jam. The story is cute and resonant.
As others have noted, it's paced a little slow in a way that I'm not sure contributes positively to the experience (although I think it's good that the "bad" ending feels like unnecessary effort). Controls feel a bit too floaty for my tastes as well.
Overall, a pleasant experience!
Your build didn't have executable permissions set. If you are on Windows, you may want to consider setting up a Linux environment or using a tool like this one so that you can set the executable permissions that will allow your Linux users to run your game without having to fiddle with permissions themselves.
