Igor Makovsky's JSW128 game Frosya the Cat was gamma-released in three major versions, all of which have historical interest and can be downloaded from the links below:
Frosya the Cat was originally gamma-released on 3rd March 2002; this here is version 2.0 (7th March 2002), which fixes many bugs.
Changes to the game: many rooms have been edited to make them easier, some rooms have been renamed, and the title-screen is significantly different. However, many bugs remain.
Changes to the archive: it removes Readme.txt, Rule.txt, Version.txt and Frosya.jpg from the archive, and adds Readme.doc.
Changes to the game: Jet Cat Frosya appears to be based on Frosya Lite Version, with the JSW128 engine upgraded to Hacklevel 9, incorporating the changes from Frosya the Cat to Frosya Lite Version plus many other changes. The critical bugs have been fixed to make the game completable, some rooms have been renamed, Rooms 138-155 have been blanked out, and the title-screen has been redrawn from scratch.
Changes to the archive: the documentation has been completely rewritten once again, with Readme.doc replaced by a new Readme.txt, List of rooms.txt and a new photo Frosya close.JPG.
