Hi, I'm glad you liked this project. There are actually many things I'd like to polish in the future since I didn't have enough time to add more content. I'll take your suggestions regarding a tutorial and the parallax effect into account. I'm not entirely clear on what you meant by the boss's ending, but I assume you're referring to the part where planet J1407B is in the middle of the map with several platforms around it. You simply have to climb those platforms until you reach the front of the planet. If the area you're in has a purple background, just climb the platforms until you reach the top. If, on the other hand, you defeated the boss that throws meteors and energy beams and you don't know what to do, it's probably a bug since it should send you directly to the final screen. If that's the case, I'd like to know in detail if you did anything to cancel that event, so I can take it into account to fix it.
