The game really needs more explanation as it doesn't seem to make much sense if you just go and try to play it. How the cards relate to the game play and the difference between gems and crystals and gold and upgrading and stuff should all be explain before you start playing.
You cant use Gems yet. so Basically no one knows for sure beside Jasper what are they for. Game is not finished. That si a big disappointment i got. But generally, when i made new account to play from start without any blockchain cards. Is really fun to play first 2 days.
My disappointment is that I expected game and all around will be finished. Like it would be real release yesterday. So from now on would be only polishing bugs. But now whole parts of game are missing and I see was already soem changes from yesterday. So my speculation is that there will still be a so called Soft Launch when all stats will reset wand we will be able to test full game fro a week or so before Full launch.
