Awesome game! Quite addicting! Why did he kill his girlfriend? I spent ages trying to find a why not to kill her, then I tried killing her and well... it worked! The music really touched it and finished it; although I haven't completed the game yet - I am on Level 18. I give it 5/5, because actually those messages affected me slightly. It made me think a bit... etc.!
The hardest one was moles but I found that quite easy. Liked it. Loved rocket gun and traps. I liked the level one before the end - awesome! I like destroying the trees. By the way I did it all with the tennis racket!
