The atmosphere is out of this world, especially for a solo dev. The tutorial was already looking amazing and you kept it up through the whole game. The SFX are really great and I'm surprised you were able to make all that art look so good in 4 days (that lighting is great).
It took me a while to understand how the game works. In the beginning I had no idea how the energy system works and in the beginning I accidentally started moving. When I wasn't able to turn back after a moment I though that it was a glitch. I guess that this is just what happens when you run out of energy. So in short I think that what I needed was a bit of feedback, for me to see how much energy I have and to associate me not being able to move with not having enough energy. The movement was a bit glitchy especially around ledges but nothing that would break the experience.
I'm surprised you were also able to put the story in your game. Many people (me included) prefer to just put the story on the jam page and focus on the rest of the game, so I'm impressed with your time management and how much you did.
Honestly, just like the rest of the comments, I also have no idea why so few people rated your game. It's really amazing. Keep up the good work and don't be discouraged by the numbers, that's not your fault. Good job!
