FAQ

Q: How do I get to the Angel Room instead of the Devil Room?

In Repentance, refusing to enter the first Devil Room guarantees the next deal room will be an Angel Room. Additionally, avoiding red heart damage helps maintain high deal chances.

Q: What is the best way to farm coins for the Greed Machine?

Rotate between different characters. Every character has a unique jam chance percentage, so playing as a variety of characters keeps the machine open longer.

Q: Are mods safe to use for achievements?

Yes, once you have defeated Mom at least once, you can use mods. However, mods are disabled for Daily Runs and online matchmaking to ensure fairness.
