Thanks Dave Microwaves Games!
The new version of FNAF Purgatory is coming out soon! The graphics are going to be overhauled to have a more realistic look, but I'm glad you like the low poly look :D Low poly modeling is very fun, but difficult to pull off!
I currently have no plans to make a free roam version of FNAF Purgatory, though I might look into adding a free roam mode or something similar, after version two is released.
