Rulebound

Rulebound is a first-person experimental puzzle game built around one idea: every door changes the rules.

Before entering each room, you choose between different doors. Each door contains a different rule that changes how you play. Once you choose, the rule becomes active and you must adapt to the challenge ahead.

The Core Mechanic

Look at a door to preview its rule, then decide whether you want to accept it.

Rules can change how you move or how the environment works.

For example:

• Reverse Controls changes the direction of your movement
• No Jump removes your ability to jump
• Slow Movement reduces your movement speed
• High Gravity makes you fall faster

The rules you choose remain active as you progress, meaning later rooms can become more challenging as multiple rules stack together.

Current Prototype

The current prototype focuses on testing the rule-changing system across three rooms.

• Choose between two rule-changing doors
•  Preview the rule before committing
• Enter the room through a void transition
• Adapt to the active rule
• Complete the environmental challenge
• Reach the exit
•  Choose another rule for the next room
• Build up a set of active rules throughout the run

The prototype currently contains four rules, with three being selected throughout a run.

Development Focus

Rulebound is still an experimental prototype. The current goal is to test whether changing rules can create meaningful decisions and interesting challenges without relying on traditional power-ups or upgrades.

Future development will focus on creating more rule-specific environments, stronger combinations between rules, and challenges that make each choice feel more meaningful.
