Same here, seems to be an issue with how the game handles save data. If you restart, then go back to menu and press continue, it remembers all the stuff you had in the old run.
I actually did get demon baby so that's how I got through the floor, but I'd still say flying enemies are unbalanced as not having the right baby can kill your run.
Yeah, the red flies destroyed almost all my chargers immediately because if they reached my defense I couldn't do anything to stop them, should be tweaked to have them come down every few seconds.
The animation for the Ragdoll boss throwing an enemy felt a bit too vague, it was hard to tell where the enemy landed so I wasn't able to move the stuff I placed on the carts to stop them from getting destroyed, maybe add an indicator on which tile it lands on.
