Go down.
Clear the room, take the door, and find a bigger one with meaner things in it. Every floor is larger than the last, with more enemies, tougher ones, and archetypes that don't fight like the ones before them. Your health carries between rooms — it doesn't refill just because you survived.
You will die. What you salvaged on the way down buys permanent upgrades, so the next run starts further along than the last one ended.
BUILD YOUR RUN
Level up and choose from over sixty upgrade cards. Buy weapons, armour and charms from a trader between floors. Hire mercenaries to fight beside you, and deploy drones and turrets to fight for you.
KEEP WHAT YOU EARN
Dying banks Bolts, spent across 27 permanent upgrade tracks that never run out of levels — including machines your next run simply begins with.
DODGE, DON'T BLOCK
There's no shield and no parry. Your dash is invincible: time it right and the blow passes straight through you.
BUILT FOR A PHONE
The gun aims and fires itself, so your thumb only moves and dodges. Your run is saved whenever you pause or leave, and picks up exactly where you left it. Left-handed controls are one tap away.
DRAWN AND HEARD IN CODE
Not a single image or audio file. Every character, room and item is drawn from coloured blocks at runtime, and every sound is synthesized on your device. That's why the whole game is a few megabytes.
No ads. No in-app purchases. No accounts. Plays entirely offline.
Descend as deep as you can. Shoot, dodge, upgrade, and go again.
