I got hyped for a second. The game definitely has potential. This is definitely short, but what did I expect from a game that just started developing?
Anyways, my VERY specific improvement is to just start the game after you throw out all the manual (can be done with the "when this leaves the camera viewport" trigger) so that new players would either have time to understand the manual or for those who understood the manual wouldn't sit in boredom for 30 seconds
