This is a great game. The level design is excellent, especially the final couple levels. How many people worked on this game? If it was just one, then this is absolutely jaw-dropping for 48 hours. I played through the whole thing and was enjoying myself for all of it.
My one wish is that you could pull objects. I'd frequently push stuff into corners by accident and then I'd be fucked because I couldn't get to the other side to push it.
