Rex Inferni – Player Guide

Welcome to Rex Inferni, a small retro platform game inspired by classic arcade adventures.

You play as a wee devil on a journey through four increasingly dangerous chapters:

Chapter I – The Countryside

Fight your way through rabbits, monks, and parish priests while learning the basics of movement and combat.

Chapter II – The Great Cathedral

The challenge increases as bishops and archbishops appear. Expect more projectiles, tougher enemies, and more difficult jumps.

Chapter III – Rome

The Pope stands between you and the gates of Hell. Cardinals patrol the city and the Pope can unleash Holy Decrees that alter the rules of the game. During shield phases, defeat the summoned guardians before you can damage him again.

Chapter IV – The Hound of Hell

Face the legendary three-headed Hound of Hell in a multi-phase boss battle. Survive fire attacks, summoned enemies, arena hazards, and increasingly aggressive attack patterns.

Controls

• Left / Right Arrow Keys – Move
• Up Arrow or Space Bar – Jump
• M – Toggle music on/off

How to Defeat Enemies

The devil cannot attack directly.

Instead, jump onto enemies from above to stomp them. Stronger enemies require multiple stomps to defeat.

Health

The devil begins with three health points.

• Taking damage reduces health.
• As health decreases, the devil becomes smaller.
• Collect wandering souls to restore lost health.

Hazards

Avoid:

• Holy water projectiles
• Holy light beams
• Consecrated zones
• Collapsing floors
• Fire attacks from the Hound of Hell

Scoring

Earn points by:

• Defeating enemies
• Collecting souls
• Completing chapters
• Defeating bosses

Your highest score is saved locally in your browser.

Tips

• Time your jumps carefully.
• Collect souls whenever possible.
• Watch for vulnerability windows during boss fights.
• During Pope shield phases, eliminate the summoned guards first.
• In the final battle, survival is often more important than attacking.

Good luck, 

Mechanics:

·       Holy water hits shrink you (watch the size bar); collect golden souls ☠️ to heal and grow back

·       Stomp enemies by landing on them; bishops and the knight take multiple stomps

·       Fall in a gap → lose one size

·       Reach the floating crown at the end: Rex Inferni!
