LOWFUEL

A Classic Cave Shooter, Built for One Thumb

LOWFUEL is a neon side-scrolling cave shooter for iPhone and iPad in the spirit of the early-1980s coin-ops. You steer with a drag, hold a second finger to fire and tap to drop a bomb. There are no on-screen buttons, no d-pad and no second hand needed, so a full arcade shooter plays comfortably on a train, a couch or a lunch break.

The twist is the fuel gauge. It burns down every second you are in the air, and the only way to refill it is to bomb the green tanks on the cave floor before the rock closes in. Every run is a race between the tanks you can reach and the fuel you have left.

How It Plays

• Drag anywhere on the screen to fly - the ship follows your thumb
• Hold a second finger still to fire your gun
• A short tap drops a bomb on the tanks and turrets below
• Fuel drains constantly - scoop or bomb the green tanks to keep flying
• Each world ends in a two-phase boss fight
• Game controllers are supported if you prefer physical sticks

Five Worlds, Each With Its Own Rules

Every world is procedurally generated, so no two runs follow the same path, and each one changes how the ship handles.

• The Ridge to the Citadel - six stages of classic cave flying, free and endless
• The Ice World - your ship drifts on the ice while geysers, laser gates and a hunting Mothership close in
• The Abyss - you float unless you hold the ship down, through squid ink and past the Kraken
• The Mainframe - polarity flips every twelve seconds and firewalls block the way to the CPU
• The Storm - sky islands, gusts, lightning and zeppelins, ending in a flying Fortress you strip turret by turret
