Physics is a big factor in this game. i find the movement can be a bit wonky.
Clicking is how you start the fight, you need to move around and shoot to survive.
The controls are fairly neat but can be tricky at times. Moving around feels a bit wonky because of the physics.
You need to manage the physics better then you think. Most of the gameplay is quick and requires reflexes.
