Thank you very much for your comments, fren!
I've been procrastinating the fixing of typos for a long time now, but I did fix both of the examples you just gave!
Custom craft is supposed to be strong since you are limited on how many cards you can craft per forge, and by the amount of High quality crafting gems you have, plus, the game gets hard, and the cards you can get from packs and shops get stronger as you play, so it isn't as unbalanced as you might think.
I really appreciate your positive comments, I hope other players agree with the thinks you liked about the game.
Sadly multiplayer was originally intended to be a feature, but I decided it was out of the scope of the game if I want to finish and publish it in a reasonable timeframe. Plus the code is so spaghettied at this point that an implementation down the road seems very unlikely :c
Anyways, thanks again for the feedback and nice comments!
