Hello first of all thank you for the feedback, you have a webgl of my game available instead of the Mac version but I could upload the Mac one if you need it!

About your game first of all, compress the folders in drive, it makes it easier to download, because drive downloads folders as zip anyways.

The game looks nice, but needs to be faster if you hold the key, I prefer to hold it instead of smashing it, the idea of the game is cool too, I like that as less energy you have, darker it gets the scene.

If you finish the game could be nice to allow the player to reset the game or something.

Good job mate!
