###Controls

Doom is usually played with a full keyboard, and multiple keys can be pressed at once.

To replicate this, we broke down the possible actions in 40 keys. Each key can be pressed (value of 1), or unpressed (value of 0).

The deltas (35 to 39) indicate speed of change (values 0 to 10), where higher values will make the player move faster on an axis.

A list of values is expected to be passed as the action (e.g. [0, 1, 0, 0, 1, 0, .... ]).

Each map is restricted on what actions can be performed, but the mapping is the same across all maps.

For example, if we want to [0] - ATTACK, [2] - JUMP, and [12] - MOVE_FORWARD at the same time, we would submit the following action:

action = [0] * 40
action[0] = 1
action[2] = 1
action[12] = 1
