Two-player game. One player uses arrow keys to navigate and the other uses WASD. You can press Down Arrow or S to shoot cannonballs if you have them. You can probably figure out the rest. And yes, it's meant to be so hard to control.
100% based off of the video game 'Shipped,' which is 100% recommended. The music is one I've made for a Pokemon project, NTPPPRM. (There's more and better music over there, check it out.) https://scratch.mit.edu/studios/31626640
