We got to play it at GenCon and pre-ordered it soon after: Portal, the Cake.
It’s a very stylish proposition. The game comes in a faux-aged box (well done too, at first glanced it really looks damaged), and first thing you’re greeted by is a fake 1970’s manual, in the style of a scientific testing protocol:
The game isn’t particularly like the video game in the sense of testing and puzzles, but is more influenced by the little cartoons that were used as advertisements for Portal and Portal 2. It’s also very chaotic. The rooms move from one edge to the other quite quickly and triggering powers requires killing off your dudes (who respawn even quicker).
The game is very low-randomness as far as dice rolling or similar, but very “random” in the sense that with so many options available to everyone else, any sort of long term planning is by-design impossible. It very quickly devolves into a mad rush and murder simulator that never progresses towards a final round, inasmuch as it just suddenly stops and whoever is ahead at that instant wins.
Only exception to that that we found is the Opera Turret card’s winning condition (usually triggered by the card Greg). That one you can sorta plan for, but since firing both of those requires 2 cakes and a 1 test subject, you’re pretty much on track to win anyways.
It’s a great game if you don’t take it too seriously. Especially since all your friends will want to try it at least once, guarantee it.
