Update, Jan 2019: Well it looks like the new Scratch update (Jan 2019) ruined this game and basically made it unplayable. Sorry everyone. It was fun while it lasted. I sent this game in to a competition for the Norwegian Donald Duck & Co magazine, and I won a Nintendo Wii U Super Mario Maker Premium pack!!!! IMPORTANT!: The tiles might spawn at wrong places if you're in fullscreen depending on your computer, so if it starts messing up, don't play the game in fullscreen. But if something still should go wrong, just press R to restart the level, and se if that helps (you might need to press it a few times). And yes, i know that some computers receive the second and third boss fights very glitchy. I don't know how to fix this, unfortunately.
