||
|
|
[1:05:47][@soysaucethekid][I know the rooms are going to fit the screen, but will there be variable sized rooms with the camera making it fit to the screen?]
|
||
|
|
[1:06:49][@dragonkinn02][When thinking of enemies, would you have classifications for AI, e.g. Level 1 approach constantly (zombie)? What would be the main levels you'd say for difficulty or reward feeling?]
