the 3rd achievement doesn't work, ran through the level 4 for 5 times till the end without killing or hiting anybody, but stil didn't get the achievement

To the developer, any game that lacks time and effort such as this will always struggle for sales. The small things in gaming matter, look at the video, walking through the long grass, the grass is dissapearing through his body, little things like this completely put me off games and will put others off. Put some effort in, or just don't bother....

I've seen a ♥♥♥♥♥♥♥ ocean of better games than this, on ♥♥♥♥♥♥♥♥ Kongregate.
