I'm sad to announce that FNaF GB will be cancelled, at least for now. 

I have run into various issues involving optimization and bugs, and decided to work on other projects, at least until a major GB studio release or bugfix. 

There is some good news, however.  I have decided to release the most recent build, which includes all animatronics, nights, and custom night.  But, fair warning, it is very unstable.
