A tiny indie that I sometimes think doesn't get enough play is Grubby Games, a two-man shop that's released two Independent Games Festival finalists (the Incredible Machine-like Professor Fizzwizzle and Breakout vs. Katamari concoction Fizzball) to date.

Anyhow, they've now mailed GSW to reveal the official launch of "...a logic puzzler of volcanic proportions: Professor Fizzwizzle and the Molten Mystery" - for Windows, Mac, and Linux, to boot. It's explained: "While on a well deserved vacation, Professor Fizzwizzle's investigation of a strange volcano has landed him in a hot spot of trouble. Now it's up to you to master exciting new gadgets, outwit the Bat-Bots, and vanquish a truly cunning villain!"

This time there's over 210 levels in three different difficulty levels, and neat concepts to help the occasionally frustrating 'trial and error' gameplay of some of these logic puzzlers: "Stuck on a level? Just use the "Show Solution" option to watch a walk-through. Made a false move? The multiple-level "undo" feature will come to your rescue. Find the action too fast? Adjust the game speed and play at your own pace." There's also a full level editor with the ability to share levels online, and I personally appreciate any game with a socially awkward-looking, white-haired scientist as its protagonist - XBLA version, plz!
