Such a fantastic entry - I really enjoyed my time with this! The only issue I had was that it seemed the cards were limited, both in damage and options, and the enemies would keep building up armour and healing, making them very hard to break. Also the lack of audio was disappointing, but I could imagine a sort of soundtrack/SFX in my head anyway. :)
The gameplay was brilliant though and there's clear scope for a really solid full release if you wanted to take it further.
It's also the best use of the theme I've seen in total! I like how it's possible to ignore combining the two hero's actions and try your luck, just to get a whiff, so it's reinforced that you have to both fight together. Also the card art and general art style was wonderful, which i'm already used to from Darkest Day. :)
