I found an earlier way to complete the game (spoilers).

SO basically I tried something and found out you can complete the game earlier than intended (oh u frictional)

Spoiler below!

When you get all the orb pieces and proceed to get captured, you can just wait in the cell for like 20 minutes (during of which the room will slowly get filled with slime) after that your screen will turn red, you hear flash-back-ish screams, and then the slime kills you... then you get the bad ending.

Sorry if it was pointed out before.

And of course this isn't as fun as going through the rest of the game.
