Welcome to my new and updated pen scrolling platformer engine! Use arrows to move and "r" to restart. Blue is solid ground, red kills you, yellow is bouncy, purple is a jump-through platform, and green teleports you to the next level. You can wall jump.
This engine features x and y scrolling, floor detection, wall detection, ceiling detection, slope detection, and moving platform detection. See inside for more details on what the program can and can't handle. To use this, simply drag the "engine" sprite into your backpack. The engine comes ready for you to make your levels, with no extra programming or work required! Feel free to use this without credit! Please send me a link in the comments if you use this in any of your games!
