I don't get items unlocked in collection after picking up them (Flip and Backpack)

That will be not that easy to do in GM:S

They randomize, i had yellow-orange pill, in one run it was Speed down, in other - Something wrong, Speed up and other...

Lil Abaddon is above, on this page (if you want it)

Hello again, know, you don't read these ideas, but i have an idea for soul hearts. You can get soul hearts by converting red hearts with Demon  Bum (Get him from start, cost 25 soul hearts) at a price of 1/4. Like 200 red hearts = 50 soul hearts. Soul hearts can be used to plant angel/demon babies, you have 25 from start to plant a Demon Bum. Read my post about Lil Abaddon, please, but i know no one cares about what i say.

I can suggest you "Lil Abaddon" idea. I know you have a "Charge System" (How i call this fillng with green black ring), so you can give him this system. You need to charge him to make his ring 3x3 with him in centre when you need it (I need it sometimes). He'll cost 50 soul hearts. But maybe... It's already in the game, i don't know, i didn't find him when i played, sorry.

P.S. About Soul Hearts read in my post below
