I have made Creepy Invaders Python game for S60 3rd edition. You can download the sis packet and sources (under GNU license) from here:
I have coded it fully on device using E61i and PyEditS60 (nowadays I have switched to Ped). Also graphics has been made on device.
- background midi music
- fast action & lot of moving objects
- levels & scores
- retro-style gfx made using ascii tables(!)
- not much else ;-)
Thanks for the Forum members for giving very useful hints and tools for development :-)
