Hollow Grounds

“Hollow Grounds” was a game about a cartographer named Piri that jumps into holes in the desert to map the caves in them. Luckily for Piri, the planet likes him so much that she changes the gravity so he flyers out of them unharmed. The player takes over that part by twisting and turning the phone.
