This could easily be one of the top few card games on kongregate, if not just on the internet, once "Multiplayer, rpg/story mode" are added. I will try to relax until then. Congrats on what's already here Nullvoid. Can't wait to see the next version.
Why do the bars for the different shields exceed even the max possible shield... The "health" bar is three larger than its max potential. And everything else is even less. Like exp bonus is like 8 less than the max exp bonus. strange.
gameplay is actually pretty decent. why not use the same interesting graphics for the enemies for the towers? Also i bet it wouldn't be that hard for you to get a few players to fix the grammer and make an update.
3/5 for the crap that is having to start over after losing, which also killed any replay value that it would have had. power adjustment would be neat. new game modes, etc.
