Prototype : Mask 505

A small 2D platformer game demo developed by two persons for the Global Game Jam 2026 in the Toulouse development center.

You’re a robot on the run from a lab, sprinting through a steampunk city with a massive zeppelin on your tail. You’re wearing a prototype mask that’s a total death trap—it makes you weak and vulnerable to all the spikes and hazards in the street.

But the mask is broken. It randomly falls off, and when it does, you become invincible. You can run over spikes and smash through obstacles that would normally kill you.

The catch: The mask always comes back. You have to parkour through the city’s most dangerous traps while you're unmasked, but if it snaps back onto your face while you’re standing on those spikes, you’re scrap metal.

How to play ? 

Z,S,Q,D / Arrows for the movement of the player, Space to jump.

Hold the direction towards a wall to attach to it.

Your mask falls every 15-20 seconds and come back quickly, but during that time you can walk on spikes.
