You use the arrow keys to move, the space key to jump, and get to the red in order to go to the next level. Press Z to restart the level. Credits to this dude: Go follow him: https://scratch.mit.edu/users/PaulRHJT/
There are as few thing you need to know, here are 3 of them. 1. This game will update when I have time to work on it, so please be patient for an update. 2. If you are asking, ALL LEVELS ARE POSSIBLE, because I have tested them, though a few levels do need the jump glitch. (It's kind of hard to do, but just hold space key) 3. This is probably the first time I'll ever use credits because I decided I need music in a platformer, so, that's all..!
