This is a really cool concept with great presentation (the art, the music, the greek vibe, the fact that you're fighting statues, I love it). I enjoy the time pressure to play the cards.
Two points:
1. The cards need to be way more readable. I'm in a big hurry so I need to be able to tell what a card does at a glance. Compare this to the presentation of Hearthstone: a big blue mana gem in the corner of every card lets me immediately know how much it's going to cost vs this game has "Cost: x" written in small text on the card. Similarly, have an icon for "restores time", "deals damage" (rather than each card having a unique icon, you could throw that out and just have for example all cards that restore time have a timer icon; all cards that deal damage have a fist, etc).
2. Balance: I beat the whole game and honestly, health was never a concern, at all. Like the lowest I've ever been is 60/80. Therefore I don't care when the enemy is doing damage, I don't care about healing or block, the only precious resource is time and the only cards I want to play are time recovery and damage. Either health should be a bigger concern, or it could just be removed and enemy just damages your clock (more focused game).
Either way, these points don't detract from the fact that this is an awesome entry. Well done!
Edit: Also: I don't think Fate Loop (replay last card) works at all? It takes my time but it doesn't seem to do anything else.
Edit: I can't see my own block or the enemy's block displayed anywhere.
