This was my first Game, I "overworked" it (much code and all textures), they aren't good but there will be better in Future. (i speak from the alien textures)
2.1 version: old -> Images i don't own -> sources given (please tell me if they don't work!)
3.0 version -> own textures :)
what i want to add next: language system and saving / loading
and better textures (currently working on it)
This game is written in Js and Html.
also its open Source: (git hub) https://github.com/ererbe/Alien-Clicker
I now you could just download the code here, but if you mod the game,(and its good) it would maybe be nice if its go in the game for all people.
