Marble Garden Zone is the only level in Sonic 3 Alone that doesn't include water.

Let's fix that.

UMGZ is a ROMhack of Sonic 3 and Knuckles that aims to spice up the otherwise standard Marble Garden Zone experience with a new challenge: the zone is entirely submerged underwater. Are you up 2 3 it?

This 1-act demo features:

• A slightly modified level and object layout
• New underwater palette (duh)
• New Goggles Monitors.....and breatheable bubbles scattered about (I'm not that mean, I promise! I even placed a few hidden bubble shields around.)
• CaterKiller..................Juniors.
• Unlockable bonus upon beating the demo

Planned Features:

• A new Act 2 boss
• A new/revised Act 2
• Hidden extra Zones, and content

Known Issues:

• There are some art bugs here and there.
