UP/DOWN arrows to switch lines. Avoid RED lines. BLUE lines are slippery. YELLOW lines give speed boost. GREEN lines are checkpoints. Sorry the game is kind of short. However, you can create your own lines in editor mode! EDITOR MODE hold 'e' while pressing green flag to enter editor mode. Press 'z' + 'p' to toggle between play mode and editor mode. While in editor mode, 'a' to add a new line segment, 'x' to delete current line segment, 'c' to copy current line segment and 'v' to paste it. 'e' to toggle current segment stats. To edit any of those stats, press the letter in parenthesis. For example, (t) Type can be edited by pressing 't'. While in editor mode, LEFT/RIGHT arrows to move left or right. Hold 'q' at the same time to move slowly, or 'w' to move faster. For a tutorial on making line segments, see this project: https://scratch.mit.edu/projects/1220412037/
