Cool concept! For next time, maybe also implement ZQSD/Arrow keys support, and some sort of tutorial to introduce the player into the game :)
Hey, adding tutorial is important, especially game with a bit of new mechanics. I would really consider adding that!
There is an arrow keys support in the game, but btw what do you mean by ZQSD? The keys are not symmetrical like arrow or wasd do.
thanks for the feedback!
