1-Player Controls A to move left, D to move right, W to jump forward. Press S to climb ladders. Check out other versions in this studio: https://scratch.mit.edu/studios/1413762/projects/
Tips: Don't touch anything red. Climbing an Orange Ladder takes you to the next level. One jump is the equivalent on five steps. You only have five lives through the whole game. Don't move when climbing ladders, jumping, or dying, because it glitches the game. Right now there are only 21 levels. In the next update (Version 1.3), more levels (including shadow levels, new to this version, and castle levels, coming in v1.3) and bug fixes will be added. Good Luck!
