I tried to make it work if you don’t have a mouse, but play with a keyboard and a mouse (you need a keyboard). If you want to learn how to play there should be a button in the title screen that says "how to play." If you can't find it, look harder.
Umm... I guess thanks to Scratch for making the coding platform. This is just a teaser, and in the real game this is also just gonna be the "how to play."
