Decent arcade game! I love the cool and satisfying effects in both visuals and audio that the game has to it, such as with the slow-mo during aiming and the explosions when smashing through other marbles. I felt like the game wasn't playing to its strengths though: with how large the map was and all the walls in the way (which were difficult to see since they weren't distinguished significantly), it felt like I had to go looking for action myself instead of the game providing a steady stream of it. It might work better to actually have the player locked in an arena with enemies that keep popping in: that way you'll never be lost looking for a fight and you'll be able to pull off cooler chain-combos in a more enclosed space, for example.
