Interesting card fighting game. The art for the enemies looks good and funny but the cards are way too busy. Usually I'm a proponent for flavor text, but I think these cards would be better off without. Have the text box for abiilty explanation only, like the healing one.
The pellet system is fun, but getting all your pellets back each time your card is removed is very powerful. I was just making my fastest attacking guy as strong as possible which worked very well to be honest.
One more note: When brainstorming ideas one of the games we came up with was "Outscale the Scaliens" so it was funny to see someone else make the same portmanteau of Scale and Alien ;D
Great job !
