BionicKid, Grandmaster games eventually get pretty easy to win against when using a solid deck. If you are struggling to beat GM, playing on Master might be the more appropriate option. Personally, the rewards for playing against the CPU seem very generous, and I think it makes sense to earn a lot more for a win over a loss.
First game was amazing...why the developer bothered to introduce a click to gather feature is beyond me. Was looking forward to the strategy that the first brought, but not going to waste my time on such a mundane requirement.
Brilliant game. When playing a game I always have a suggestion or two in mind, but on this game I wouldn't change anything (at least after playing the first 12 levels). Perfect balance between simplicity and complexity. Tutorial wasn't overbearing. Learning curve was smooth. Just great all round. Looking forward to checking out any other games you have released or will be releasing.
I like Undefined, but I'm getting tired of him releasing games when they are not finished. Cardian is the most severe example of that so far. There are some good ideas in this, but few of them have been refined enough for the game to be enjoyable. And the UI isn't remotely friendly; a game shouldn't feel like work.
