Submit portable freeware that you find here. It helps if you include information like description, extraction instruction, Unicode support, whether it writes to the registry, and so on.
FLaiL is a physics-based platformer with 80 stages. Two player co-operative play is included, and a third player can jump in at anytime by using the mouse cursor to drop bombs on the stage in an attempt to disintegrate the other players. There is a level editor and meticulous stat tracking, as well as other unlockable features.
Unless it's changed since I tested it (maybe 2 or 3 weeks ago?) it registers file types for its save files and level files (you can make your own levels!). This means it uses the registry, rather intrusively.
