About This Game

Sky Furnace is a side-scrolling shoot 'em up with roguelite progression, set in a dieselpunk world. You fly a warplane: three minutes of combat over islands, canyons and clouds, then the boss arrives. Downed enemies drop XP; every level lets you pick one ability out of three, and by the end of a sortie those cards add up to a build of your own. Some card sets lock together into a mega upgrade.

Campaign

19 levels across seven chapters, each with its own enemies, bosses and weather: wind pushes both your plane and every bullet, storms strike with lightning, updrafts pull you skyward.

Seven planes, seven characters

From a fast scout to a heavy bomber and a carrier that launches its own wing. Each has its own starting cards, its own right-button ability and its own way of flying.

Hangar

Bolts earned in every sortie stay with you and are spent between flights on new planes, a talent tree and paint jobs.

After the campaign

Twenty Ascension tiers, an endless mode and a weekly challenge with a shared board. A casual mode is there for those who want it easier.

Two players

A wing of two pilots on one computer: keyboard and gamepad, or two gamepads.
