Mind your sides

There are 4 sides, castle with 4 sturdy walls and 4 hordes of enemies.

Fortunately, each wall has infinite amount of arrows to shoot and molotovs to throw.

By killing enemies you gain levels, but be ware of side effects. Level ups are not only for you, but also for your enemies.

Try to survive as long as you can....
