Click the mouse, or press any key to trigger the rocketship to go up. Else make it go down. Navigate your way through the 2D GD-based off the game and make it to the end, where you will be really happy. Trust me. You might rage, but once you beat it, you'll be as happy as.... happy! I added a mini-portal, a normal portal AND a large portal. I also added Speed Portals
