Introduction

Why bother reading the introduction? This is just a simple Five Nights at Sonic's fangame based entirely on FNaS: Maniac Mania (both og and official remake) and its cancelled extensions (MM+ and MMI).

This fangame will include characters from FNaS 1, 2, 3, 4, 5TFC, RC and whatever else I will think of. Yes, this game will include skins for multiple characters, such as the 4DLC cast, 4HE cast, etc.

Progress (For whatever, publicly available beta, demo build, you name it)

Not revealing anything yet.
