this isnt a great type of game to try to make if you only have 3 weeks to develop it. Card Games, if they are to be any good, must be complex and have strategic depth.
Dont know what to do on a level? Tips, Levels 1-20 click walkthrough button if lost. On another note, what kind of aliens intelligent enough to get here dont have any kind of protection from microorganisms?
I just want to say that if you want to be taken seriously, you have to respond to feedback in a professional manner. Arguing with someone over their opinion of your game is pointless and makes you look bad as a developer. Instead of responding with "wtf no you are wrong" say something like "i will do what i can to fix that" or nothing at all. It makes people more hopeful about the potential of your game. If you act like a jerk about negative feedback, you may find people not only avoiding this game but other games you may create in the future.
