Arrow keys to move the yellow square. Try to avoid the lava. There will be obstacles that will block your way. The blue blobs will slow you down a bit. The green blobs are land, and the red blobs are, of course, lava.
Thanks to my brother, @I-LIKE-SCRATCH_920 for giving me the idea of this scrolling platform. This was so easy to code since coding the scrolling was just moving the blocks left and changing the costumes. This project took nearly an hour to make, non-stop.
