In Gnah, players poke around the heads of giant monsters, interacting with their faces and then turning them around to mess about inside of their craniums, hoping to eventually find the exit. Playing with the inside of a monster head affects the outside, and playing with the outside changes the inside. All giant monsters are beautiful on the inside, of course.
Previous iterations of Gnah featured a tiny boy inside of the monsters' heads, but after playtesting, KO-OP Mode has decided to ditch the character in favor of liberated gameplay:
"When you were on the outside, you could manipulate any part of the monster, and when you'd flip to the inside, you could play as the kid and interact with objects within the kid's reach. Unfortunately this turned out to be not very fun – the more free-form play of the outside of the head was much more enjoyable and it was frustrating to switch to the kid and be limited to only what they could reach."
Gnah had a spot in the GDC Indie Megabooth, and responses to the gameplay tweaks were "awesome," KO-OP Mode says.
