I really liked the dithering of the background combined with the card art. It's got a vibe for sure.
The rules were simple enough to get, though as things got more hectic, I wish the UI would help me see the combos so I could keep up with the draining health bar. I really like this grid + solitaire-esque style game. There's definitely something here and I would love to see a more fleshed out version with more card based rules and mechanics. Still, very fun play as it is!
