Thank you once again for your feedback, I really appreciate you commenting on my games. I really need to find a way to repay you for all you kind words.
I think this is one game that benefits from being played on an actual Gameboy as the levels begin where you left off (died) and the invincibility can be helpful on some levels but doesn't help you at all on others.
The guy (juicelizard) who made the original version has made a few game here on itch and also has a couple of Dreamcast games in development. He actually made a very well rounded character in squarenose, I wish I had the talent to create something as good as he has.
