ill summarize
level 1: introduction to concept
level 2: introduce the the three players interacting
level 3:pretty cool challenge
level 4:the darkness makes it so it feels like the end as all movement just pushes you back(or at least appears to) but since all levels end at the bottom left corner its a "hold right to win level"
level 5:"YOU WANNA SEE HOW FAST I AM" -yellow "the mentally insane" box
id think that a sense of moving forward whether tension or curiosity should be applied at level 4
i would like usage of a larger room so that you cant just go directly to the red cube but would have to use a path from blue to green to red, alternatively, you could've used darkness to prevent character swapping. i don't know conditional swapping is something one my mind here
i like the text boxes each player uses.
