Those two bats follow you further than I'd like them to, yeah. Seems to me, I either leave them as is or have to simply remove them, don't think putting them further to the left will change much.
Right now, I'm casually working on the Sting Chameleon stage. I definitely want to add a completely new enemy, preferably a miniboss as that would be fun challenge.
I appreciate your feedback, don't worry about it. I havent seen your MMX stuff, can you point me out to it?
