Really fun and polished game, great job!
Love how the ostrich run animation and music make for a frantic atmosphere. And the "hide head in the floor so cameras can't detect you" is hilarious. Great stuff with muffling the music during it.
I can also see a lot of care went into the menus and UI with responsive buttons.
One small issue I had is that with the camera angle it was sometimes difficult to notice rooms on lower right.
I also found a hilarious visual bug where when you smack your head against reinforced wall (witout other ostriches so not breaking it) and run away from it then sometimes your neck streches to 10x it's size and sloowly becomes normal XD
