About the game...
First and foremost, I would like to thank you for adding this game to Newgrounds, where i do all my reviews.
I played Spectromancer on a different site first, and quite enjoyed it there. My only real complaint was the lack of single player depth. Dont get me wrong, there is almost nothing wrong with that, TCG's are all about PvP. But I like TCG's where I can have my PvP deck AND my PvE deck, and in most cases I actually enjoy using the PvE better because it's a Deck that isn't just absolutely Tinked to get the most out of the cards you have. That being said, I love the game otherwise.
I've seen some complaints about the Unbalanced Nature about the starter decks, and I've played as every class, and can only find some minor tweaking that would be needed, but otherwise, its all strategy, and its a TCG more about skill and resource management than Luck of the draw, what with there being no luck of the draw, and that has to be my single favorite thing about the Game.
All in all, you did a good job, and I hope you keep making improvements, and expand the Campaign a lot more. If you need any suggestions, I"ve been playing TCG's Since MtG alpha. Good luck with any future changes or submissions, and I hope you keep it up.
(Don't take the 8 stars badly, I take the rating system VERY seriously.)
