make sure you test on macs!
The reason some people are saying it has bad controls or its laggy, is because on Macs in Firefox it is VERY VERY laggy. It is simply unplayable. Although if you use Safari it does fix things..
Although I am not sure if this is Safari specfic or even Mac specific, but I watched a preview youtube video embedded in the mochiAds service for the ninja guy or w/e.. Then whenever I pressed F, the screen would go into full screen mode. So this would happen every time I needed to repair a door.
A full screen mode would actually be good since I died because I clicked away from the screen and it hid the window behind another window... Didnt get back to it fast enough.. I was dead.
It was fun though!! 10/10 if you fix the Mac related stuff and include full screen.
