It's almost tradition that during Eastern Holidays Warsztat members organize special edition of Compo (game developing competition, check). Randomly chosen topic of competition was "A game with particles-effect, Zombies, arrows and deadly spikes". Quite creative.
Finally, except me, there was only one participant took part in Compo, so there was no results. If you are interested in my game, download it here: EasternCompo [290KB]
(Readme and gui are in polish, sorry).
