This was my first Game, I "overworked" it (much code and all textures), they aren't good but there will may 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 (I will do it if I have nothing different to do)

This game is written in Js and Html.
also its open Source: (git hub)  https://github.com/ererbe/Alien-Clicker

Mod the game if you want, and tell it here. :D
