LoL ok, I knew the mannequin would kill me if he caught me. And he was just walking but... damn every time he got close I jumped! The gorilla tag movement was great. It was a bit hard to grab the keys sometimes but fun to escape the mannequin. The movement you implemented was really well done, solid.
I wish the theme of the world could have been tied together a bit more. It's an office, there's a mannequin, and you are... a tiny jumping something with black dots for hands, collecting glowing keys? All the mechanics are there, but it's missing a little something to tie it all together. Like does one key do something? If you need all the keys, maybe it should be like a "piece of a key" that you pick up until you get a FULL key and then you can escape or do something with it. One key assumes you can unlock one object. Anyway those are my thoughts, I had a really fun time escaping the mannequin!
