Press any key to start. This is a one player game. Use arrow keys to move. If you touch the grey line, you lose. Recommended in Full Screen. If you want to go faster or slower, change the variable "speed".
Surprisingly, my first game was not a "pen" game, unlike most other scratchers I know. This is based on two player game. Try that as well. https://scratch.mit.edu/projects/98769195/
