Why am I a cube?

That's my first game I made for a Jam, so I hope you like it!

"Why am I a cube" - Cube

For this game, I had the idea of creating a universe where the main character was actually a human, who ended up entering the current game world and lost part of his memories. During the game, You will notice a green cube, which will be very important in "Why am I a cube" lore. As the game progresses, you may notice that there are disabled cubes on the platforms, as if their source code were stolen, as if your life had been stolen. My idea was to expand all this lore better, but unfortunately I didn't have time to finish it. I'm working with optimization yet, so it may crash if you increase the graphics quality. I made this game completely alone, and the theme was literally "Puzzle". The game have some bugs, and I will fix it and update as soon as possible, so if you see any bug, or have an idea to improve the game, please tell me in the comments!
