The updated version of Tennix, the open source tennis game is now available in Maemo Extras for Chinook, Diablo and Fremantle (anyone with Fremantle hardware care to test if it works correctly? Thanks!). The 1.0 release has been announced to the public in February already, but I have only now had time to create a proper package for Maemo. It plays fine with stylus or the D-Pad.
Here is a gameplay video if you can't wait to download it onto your tablet.
