An interesting mechanic and premise. I rather liked the game – played it solo acting as two separate penguins. The simulation is a touch complex – there’s a lot of little bits that I only noticed on third or fourth re-read (like the fact that you need two players to mate… hint – don’t make all the player penguins the same gender – or ignore gender). This is a game I would add to my “I need something complex to distract myself with” pile along with generating Traveller characters. Downsides to my mind – while the terrain etc is an interesting generation technique, it doesn’t appear to do much later in the game other than depending on where you travel to make a nest will determine distance to the sea, needed for hunting. It’s pretty open framework – had to make a lot of “house rule” decisions – e.g. if the challenge occurs in the sea, but not during the turn you’re hunting, do you have to deal with it? Also, figuring out what use the special abilities might have. Again, this is me playing it solo – not the two player as designed, which would lead to more interesting interactions.
