This game ist totally hillarious while being absolutely serious fun at the same time.
All you have to do is chasing animals with your UFO to your mothership. Over time the levels get more difficult by adding obstacles, introducing various animal types to chase and even some enemies like wolves that can get really annoying while trying to do a double gold star rating on some of the levels.
As a child I had a toy that was an enclosed A4 shaped plasctic case with a clear top covering filled with little plastic pieces that you had to push around with a little truck that was moved by using a magnet under the bottom of the case. Somehow this game reminds me of it.
I had great fun with this thing during my childhood and man am a I having fun with this game here now.
I can totally recommend this game to everybody who likes a deep challenge from a game that looks so cute while being brutally difficult at times to master.
And the music ... you've got to listen to the music in the main menu. Man I love that sh*t oozing that 70's scifi flair out of every inch ...
(Though I have to admit while it's perfectly playable with your standard X-Box Controller, playing with your keyboard and mouse could get a little bit complicated as the difficulty keeps rising in the higher levels making it nearly impossible to win the missions without a controller ... you know what? This game is the perfect excuse for you to finally get yourself a Controller too ... I'm serious!)
Check the demo, have fun with it and then go an buy the game. It's totaly worth every penny they're asking for it.
