New testing features and quality of life improvements are now live.

GODMODE TESTING SUIT

A new testing suit can now be unlocked from the Player Suit Selection screen.

Keyboard: Type GODMODE

Gamepad: D-pad Left, Right, Left, Right, Left, Right, then Reload

The suit regenerates health every second and has a fully emissive skin. It is intended as a testing tool, making it easier to explore rooms, enemies and mechanics without constantly restarting a run.

WEAPON SWITCHING

You can now switch weapons using:

Mouse: Scroll wheel
Keyboard: Z / X
Gamepad: D-pad Left / Right

BACKPACK SYSTEM Updated

Weapons with 0 ammo are now automatically removed when returned to the backpack.

This means empty weapons will no longer stay in the weapon rotation during combat.

ROOM DEBUG IDs

A small room identification code is now displayed on the right side of the screen, below the radar.

When reporting room-specific bugs, please include this code when possible. It allows me to quickly identify the exact room, layout and enemy setup.

EARLY FLOOR 2 MUSIC

Early work-in-progress versions of the new ambient and action tracks have also been added.

These are still raw versions, but they give an early glimpse of the atmosphere planned for this floor.

KNOWN ISSUE

The bug that allows the player to leave certain rooms while the door is still closed is still present in this build.

The fix is planned for the next update.

For now, if you encounter it, please include the new Room Debug ID in your report so I can identify the exact setup.

Thanks everyone for testing and sending feedback!
