Undertale - Neutral Run Disbelief

Q: Are you Toby Fox? Is this official?
A: No.

Q: When will this game be finished?
A: We don't have an exact release time planned. But it's most likely going to take a while. However, we will be releasing Acts after they are finished. After all of the Acts are done, there will be a final game including all of them.

Q: Is this game related to any other disbelief fangames in any way?
A: Not really. While it is based on FlamesAtGames' Disbelief, it's still a lot different from it and any other disbelief fangames.

Q: How would Neutral Run Disbelief even work? It's a neutral run, so there's no way this could work.
A: We've made it work. Maaagic.

Q: Will the game be free?
A: Of course.

Q: Can I join the team?
A: You'll have to join the discord server and show some examples of your work, if you're good enough, you'll be able to join.

Q: How many Acts will there be?
A: As of right now, we have 3 Acts planned (including Act 0), but it's possible that there'll be more.
