For your consideration: (playing version 0.4.3)
For episode 1 you can also use the arrow keys for movememt as well (up arrow forward, down arrow backwards etc). But in episodes 2, 3 & 4 have the up arrow moving you backwards and the down arrow moving you forwards instead. Please can you make the other episodes match the first one. As a lefty the arrow-keys are easier to use than the standard WSAD-keys.
Would have thought this sort of games concept with discrete episodes might be more suited to using some sort of base game 'player' and each episode being seperate downloadable modules (DLC).
