Oh, and "Sacred Pact" mentions +2 gold generation; but I gain +2 crystal generation. Might want to change that, either the text or the mechanic. :)
Thumbs up!
I would like to see hot-keys for summoning units or putting the summons bar on "auto-summon". Either would greatly increase gameplay. It would also be nice if I could tear up multiple cards all at once. Perhaps a multiplayer but I find the game much satisfying. I like the mix-up like "age of cards". 4/5 from me. :)
You know, I like that there's a minimum of numbers. It's only so often I get to see that time takes as much as it needs. I'm quite certain this is not an aware reminder of how we use time, but as we grow more and more efficient and begin to see everything in numbers we start to forget what those numbers represent, and why we put them there in the first place. I'm not saying back to the stone ages or anarchy is the way or anything else one might decide to interpret, that's you interpreting!
The 2x abilities was too OP. In my opinion, I would make so each ability has a cooldown of 1 round. So that you may use 1 fireball and 1 sleep/teleport - not 2 fireball. That would have helped a lot with the gameplay. Then range wouldn't have been as OP on the players side and the computer could have managed to actually do some damage. I hope I haven't been too intrusive, yours dearly, A player.
Another bug, if you fast press an upg with 200 g, you can add as many upg as you like and end up with less than you had with equal many upgrades as minus. That sentence sounds fishy no matter how I try to put it. ._.''
I like it that it's few powerups, hard and fun/frustrating to play but what I propose is to allow the powerups stay forever until picked up or changing stage. Having to run into massive hordes of enemies to pick that very much needed powerup instead of concentrating on my priorities to survive is rather suicidal at times, because if you don't reach for it: you'll die soon. If you do: you might die now.
