Seeing this thread up in the list, I thought "ah, what's the point of checking it, no way there's actually a new part, someone's just bumping it to keep from sinking", but then I scrolled down and...
Yyyyyeeeeessss!
This setting allows for a lot of possibilities and it's always exciting to see what creative use it is given in each new part.
I hate to be the guy, but someone has to point out that this wouldn't have worked, as the left hemisphere of the brain controls the right half of the body and vice versa. But let it not bother you, as this is gurochan, not a biology class, so fun comes before realism.
I didn't have problems understanding the ending, the last couple of lines make it quite obvious in my opinion. The beginning, on the other hand, felt like a mess... I mean, I get that it probably was supposed to feel that way to convey how the characters felt, but it got a bit too far with it. It took me actually reading it for the second time to get what was going on. But maybe it was just me, I dunno.
Anyway it was fun. I enjoyed this part much more than the one with Alyssa in the backpack, and certainly looking forward to seeing what Alex will do with suddenly having two sisters.
