I don't know if the developers are still checking the page or not, but I hope so. I am going to personally take the time to thank Richard Garfield and Skaff Elias for changing my life. I have been playing Magic the Gathering since Ice Age (my best friend and I pre ordered a box of Ice Age and split it. He pulled a jester cap; I pulled a Gravebind :-( ). I've been playing Magic on and off ever since, and I have a collection that even I find absurd sometimes. You guys are truly geniuses among men, so I thank you for your contributions that have changed the lives of millions of players around the world for nearly 2 decades. And now I get to play your newest creation on Kongregate?!? That's just icing on the kake.
I got the last Challenge down to 1 card and it locked the game. It refused to choose either power or draw a card, forced me to quit. Other than that, not bad. I've been playing card games for years, and this is one is all right. It has some interfacing issues, and not being able to use deck build for regular missions kind of stinks. Try not to end up like Elements in multi player though...
I don't like that there is no way to recover spent skill points or at least clear the saved game data so I can start over. The game is ok. Some of the level descriptions aren't legible on the Level Select screen.
 "Spectromancer: Gamer's Pack"){kind=icon}
 "Mytheria"){kind=icon}
 "Infectonator : World Dominator"){kind=icon}
 "Necronator 2"){kind=icon}
 "Vector Siege TD"){kind=icon}
Thanks for your kind word, I will convey your feelings to Richard. Hope you will find the next version on Kongregate, very soon
