This is a very innovative start of an idea. If put in a real multiplayer game, it will be dope AF.
However, at the heart it is still carrying and throwing a cargo to a hoop.
I suggest adding simple deterministic AI to P2, and then this puzzle may get back some of its depth.
That said, i should look at its intention and picture it happening right in the middle of a multiplayer game, then the mood is really here. I really want to pick up that one disconnected guy and throw'im out of the window, or, at the red goal.
Cute graphic and nice collection of sprites. Especially liked P1 lifting its tiny arms. The box manipulation mechanics and the throwing mechanics are very well implemented and very smooth. Well done
