We were 2 web developers, with one have little knowledges in making video games (Started some games but never finished). One person who worked on fun personal projects on Blender, and one Web designer/ergonom. And two of them is guitarist ^^
So all sounds was self-maded. And yes, some environment sounds can be disturbing (Maybe annoying, we wanted the player feels becoming crazier with the time. The bells start from 1 for level 1 to 12 hits of midnight for level 12).
We imagined a more deepest story behind this game but we hadn't the time for unfortunaly. Maybe we'll try to finish it later !
Thanks ! =)
