While the concept could have worked, the logic behind it is just retarded. Humans would not attack an alien unless it attacked them. As far as we know, that could provoke interstellar war or something. Instead, we'd try to communicate with it and befriend it.
@Darkguilotine: I noticed I had the same issue, but loading up an old save and destroying a few towns seemed to trigger it, because I got the achievements afterwards.
Okay, this has got to be one of the worst Flash games I have ever played. There's no gravity in space unless you're close to a planet or star, which means jumping between platforms would be impossible. However, considering all the platforms don't seem to fall down, I'd say we're not close to a planet in this game. The only enemy you face is a poorly drawn spike, the "You Win" area doesn't end the game, falling off the platforms does not end the game, you can walk on the "You Win" text, there is only one level and it is a very short one at that and I noticed at one point in it, it said "This way". Normally I wouldn't mind the game helping me, but in this case I do. There is only one path to take and you only pass a few screens length before you come across this text, making it entirely pointless.
This was a pathetic game. The graphics were lacking, the gameplay was broken and the level design was horrible. 1/5
1olink, how would it even use achievements?
The only things you can achieve are a fast time or a small number of clicks on a level and that doesn't seem like it's really worth uploading an API for. If a game is worthy of getting achievements, it's a game where you can do a lot of different things. Puzzle games tend to be the least fitting. Action games tend to be MUCH better.
