Use the arrow keys or WASD to move the dark green dot. Try to get to the lighter green dot. If you touch the bright green background, you have to start that level over. There are 8 levels. There is a secret key you can use in lvl 1 that will teleport you to another level.
Thanks to @heffasnacks for the original idea on their featured project "Rebound." Link below: https://scratch.mit.edu/projects/288095886/ I made the last two levels move every three seconds on purpose. Yes, it is possible. I beat the game with 14 fails. And, all levels are possible with a size of less than 50.
