that's the problem with the directory "/usr/lib/games/ufoai/base/ufoai" which mean nothing.
Your game.so should be ATM at "/usr/lib/games/ufoai/base/game.so". Maybe you can copy it at "/usr/lib/games/ufoai/base/ufoai" or in your home at "/home/mundus/.ufoai/2.3/base"...
And please, where come from your package? Which version...
