Not sure what exactly happened but a few rocky poops kept pushing my defences and it somehow misaligned the grid slightly downwards and to the right, it was on the first loop (after beating middle horn once) in the second level of the ark.
Also i feel like allowing the player to get more babies after looping would be nice, maybe just make it so you get one in the shop that you can buy after a boss?
(And might be just me but i feel like mulibooms and the rock poops are a pain to deal with and there is entirely too many of them)
