I have a laundry list of issues with this game, and that's just after the first couple quests. There seems to be no way to get a good look at what cards your opponent actually has on the battlefield, besides their bloodlust, rage, and life. The fact that equipment is put on a creature at random just seems like lazy programming and makes any form of strategy impossible. There is no reason to run anything but creatures when equipment seems to vanish into my graveyard about half the times I use it. Any play besides a creature puts you behind on the board, and once either player has even a slight advantage the game dissolves into one player being trampled while they try to catch-up.
I was so freaked out when I found out there were physics. I literally shouted at my computer screen. Only real problem I have with this game is that the blocks don't always line up on the grid perfectly causing me to lose control of a block when it barely scrapes another...
really great game, if I was forced at gunpoint to criticize I would say it got to the point around the 15th day that I feared no onslaught because full health was maybe 1500 gold away, but at that point the game was essentially over anyway. I really enjoyed the game overall. One of the best twenty minute games on Kongregate. By the way the discovery of the 500 gold health button was one of those "holy crap I'm dumb" moments for me
