Not an exciting concept.
I played this game solo just to test it out, and it's not good.
I actually found a bug where you can keep holding the left mouse button instead of simply clicking it to make the marble accelerate after I shoot it.
The text needs a much needed proofread, both in the game and on the game's page.
The game itself doesn't really make it clear that you're supposed to click outside of the circle boundary to shoot the marbles inside of it. On that note, aiming and shooting to the outside of the boundary is possible for some reason.
The instructions state that I can use the right click to use a skill, but right-clicking does nothing. I might be missing something though.
The game seemingly decides who won the match as soon as all of one player's marble is out of the boundary, while the marbles are still moving.
The game's physics needs some tweaking. The marbles slide way too easily on the playing field(is it supposed to be made from ice?).
Overall, a lot of work needs to be done. But I wish you luck!
