Downwell

In Downwell, you descend into a deep well filled with monsters and traps, equipped with the Gunboots — a set of boots that let you shoot bullets from your feet. You’ll be using it to clear your way of enemies, or as a way to slow your descent using its recoil. On your way down you’ll find different guns, shops with helpful items, and upgrades like explosive balloons or a set of silverware to eat your foes with. The well is randomly generated, so no two trips down will ever be the same. [Playstation.com]
