Version 2.2 is now available

Isostasy Version 2.2 contains more bug fixes, slight tweaks to improve the gameplay experience, and a BIG new secret for the most enterprising explorers to find!

Some new features:

• On the Title screen, while holding select, press right for PAL mode or left for NTSC mode. All this does is adjust music playback speed to account for the different framerate on consoles from different regions. No other aspect of gameplay is affected, but I felt at least playing the music at the correct speed could improve the experience of anybody playing the game on a PAL region console.
• In the Windows PC edition, the Pause/Break key can be used to return to the Title Screen without having to close and reopen the program. It behaves just like the Reset button on the NES.
