Welcome to Terry the Cherry. WASD or Arrow Keys to move and you touch yellow to advance. Press "x" to enable...hard mode (be sure to have your volume up for that). 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 I can do every single one of them. Currently, Terry the Cherry is in version 2.0.0. Updates to the game appear regularly, so if you beat the game, there's always going to be more.
Thanks to @ejb0529 or Da Blue Guy for also being knowledgeable in code and helping untie some knots in my acceleration.
