Get aside!!!

Too random,I mean, although the behavior of the R is predetermined the fact of putting so many in such a small square it makes his behavior in general very random at the end.Hahaha I know it sounds like contradiction but if you think about it well it is not. But good to know that this level has been created in just 32 seconds too...Thanks for sharing @Grapehool

Very weak game play - I didn't win and tried twice.

All those Reds crammed in a small space just means they keep locking together and then it's impossible to get B past. I got lucky on the third go and managed to get through.
