Rooftops are jumped, skulls are thumped and a man falls on his wet bum in Thief-esque Project Shadowglass' latest trailer

Shhhhhhh. I'm trying to sneak into this poor bloke's castle. I'm doing it all stealthy, sneaky, and shadowy-like. I'm climbing in windows, jumping across rooftops, bamboozling guards. I'm taking the gold and gems while letting out a cackle deliberately stifled enough that no one can hear it but m-. Oh, bollocks. Hello, owner of these valuables. I hadn't counted on you walking in at this very second.

That's the sort of thing pixel art immersive heist sim Project Shadowglass will have in store...
