A and D keyboard keys are the movement keys for left and right respectively for Player 1, while Left Arrow and Right Arrow keys are the movement keys for Player 2.
We also have ascensors that the players can stand on and use to go up or down the level, these could be activated using buttons or levers depending on the level.
In some of the levels there might be some rocks/boxes/crates spread around the level
that the players need to interact with to progress into the next levels
