Nice little homage to super meatboy and the gameboy. Next time elaborate on the world outside the gaming, as others have stated use corrupted spites like missing no. and don't be afraid to take some inspiration from IWTBTG with random obstacles, even some MGS psycho mantis style would make it amazing. Good concept over anything so I gave you a 4; expanding to beyond 10mb would be getting closer too 5 star from me.
Keep up the good work and thanks for making this!
