Interesting take, Ted's mental breakdown made me laugh x) I think there's a few problem though:
It's weird to have to move the characters one at the time when they are treated as close. You should add some way for the characters to follow each other at least on straight lines.
The ennemies seem to spawn only when Ted (or Rosie and Ted) are close enough. It doesn't really feel great to scoot with Rosie for nothing.
There's a visual bug where if you hold an arrow key while switching character, both characters will trigger their moving animation when moving.
