Welcome to Terry the Cherry. WASD to move (unfortunately I cannot do both wasd and arrow keys because of acceleration problems) and you touch yellow to advance. Press "x" to enable...hard mode. Don't worry if you can't get a level. That is normal. If you think a level is impossible, it's not. I have tested them all and can do every single one of them. This is just a rough draft, and I will make a better version with more levels.
