Nice work, I like how this game plays with the conventions of 3d games and has interesting choices for the player. The use of text meshes for the instructions and guidance throughout the game is well done, but I think the text could be a bit larger, its hard to read at some points. There is a nice sense of humor, like going up the platforms to find a message and then having to find the portal behind a mesh that has no collider. And I like the end level with the meme image. The portal in the last level doesn't seem to go anywhere, not sure if that's an error, but you should either remove it and have another ending or have it go somewhere so its not confusing.
