In order to make it 1s1s1c (one sprite, one script, one costume), I couldn't make multiple levels. So, after you make it to the other side, press the green flag to continue to the next level. Refresh the page to reset. So, first it randomly generates blocks. Then, go to the other side. Oh yeah, turbo mode (shift click green flag) is helpful when the levels are generating.
My first 1s1s1c project :D Credit to XUDI for the platform engine. 12/31/2014 - I realize that because of 2.0, it doesn't stamp in the color that color effect sets it to. All blocks on the terrain are green instead of just the top one being green and the rest brown. 3/8/2016 - This is no longer the case…
