Overview
Released onto Steam Early Access in late June of 2015 by Studio Monolith.
Gameplay
Single Player
The main focus of Polyball is tight controls and heavy physics. A lot of other marble games are very responsive and floaty, whereas Polyball favors momentum and subtle movement.
Multiplayer
The multiplayer of Polyball is so different from the single player it may as well be a different game. There are a variety of modes (with more being added) but the main modes are Battle and Circuit. In battle mode players choose from one of six weapons which they are stuck with for the entire match. There are about 16 power-ups to pick up during a match - ranging from double jump to an AoE stun, to a rage mode that triples the player's size.
