Eli Piilonen – he of clever (and admirably top-hat-clad) time-echo puzzler The Company of Myself, among many others – has plans. Big plans. He’s making a stealth game – of which, happily, there are roughly a billion of these days – but his is different. Very different. Excitingly different. But also worrisomely different. Different different different. There. Now you probably hate that word. Anyway, the still-untitled sneaker sees players heist their way through increasingly complex procedurally generated levels of a sci-fi office building. And if you fail? Well sorry, friend. No do-overs.
