Hulabee Entertainment developed a proprietary engine initially for its adventure kid games.

The internal name was probably 'Sauce' as referenced in the executable.

$ strings MoopTreasure.exe | grep -i engine
ESauce Engine Error: %s
name="Hulabee.ESauce.Engine"

This repository contains:

• a rewrite of the engine using SDL2
• a version of whisk.dll to enable VM opcodes tracing
• some tools to extract and convert assets from .pan and .gg files
• some miscellaneous information about the engine and the games
