About the game
Bobr turbo: craft cars hands you a pile of blocks and asks for one thing: a machine that can win a fight. You drag parts from your inventory into a build, adding boosters and weapons until the thing looks ready to crash into something.
Chests hand over loot that grows your parts supply, and upgrading makes a build tougher, quicker and harder to stop. Once you are done, the arena fight runs by itself, so the thinking happens before the clash. A loss tells you which piece to swap out next time.
