You are locked in the cage and there is no way out. The only way to survive is to destroy crates that are falling from above and avoid various traps that can kill you. Destroy crates and concrete obstacles with your gun and find a free spot to step in.
It's an avoid being crushed, smashed, spiked action game! R U actiony enough to survive the game?
Stay focused and destroy the crates as fast as u can. Also, dont forget to collec the coin - u will need them to upgrade and get new and better weapons etc as u progress through the game.
Good luck and hopefully one day u will get out of the box... one dayyy
