It's an ok idea and pretty well made, though I would personally like there to be more cards so you could play with different strategies instead of the same thing over and over. However, I don't like the game because it's based too much on chance, and being the unlucky sod that I am no matter how well i play I still might lose. This may sound weird, but when you've tried a 120% chance NOT proccing, you might feel that way too.
Great idea and well made, unfortunately level 21 brought it down from 4 to 2/5 for me. It may just be too late in the night, but I couldn't see any pattern, and a trial and error "puzzle" with that many possibilities is nothing but annoying.
Not a bad game, got me a few laughs. To the people below, hard is not supposed to be equal and there are more ways to win than you think. A little tactical placement makes your own candidate very powerful.
I got 1000 points as well with much the same setup as Gwarth, just some other upgrades; 3 knights with +1 shield & +2 health, a mage on the block with maxxed dmg and +3 chain and a healer with +4 healing and +1 range. Only tricky part was when the enemies had a lot of knights and started flanking me or focusing the healer but it was easy overcome.
It's a great idea, and good 2 dimensional implementation. However, there are so many glitches (especially in level 37 and 38) that I started shouting and throwing things around when my boxes disappeared or were randomly teleported around the level. If the glitches were fixed it'd be very good, although a little easy.
