It's a really cool idea and a unique take on the FNaF gameplay style and there was a decent bit of work put into this but...
First off: the game was rather very slow to the point it became boring and was taking way too long. It's good that it was going slow at the start so there was time to adjust, but maybe there could be a "switch" to speed up the process?
Secondly: why not keep the labels for the controls or at least have an option to see them? It became difficult to remember what was what and I almost made a couple of mistakes because of it.
Finally and most importantly: my game crashed... I worked kinda hard to get to the end, obeyed all of the clients requests, just for it to crash shortly after taking a look at the black goo client.
It really isn't bad and has good elements, but needs a lot of refining.
