Nice card game, I've never seen this concept and this is really cool. 

As a fan of board games, I think that this game has a great potential !

Really cool concept! I liked figuring out the right order of cards so that you gain enough strength before attacking, but not letting the opponent attack you too much. I know you ran out of time, but I think it would have been good to make the card slots a bit bigger to show the graphics better while there are locked slots (like having the locked slots stacked to the side to show the unlockable possibilities).

The action also happened very quickly, so it was hard to keep track of whether my plan was working (it did work though haha!). Overall well done though!

The concept is interesting. It's tricky to play the cards in a way that damage the opponent but dosen't affect you. It reminds me the card puzzle in the magic or yu gi oh games.
Very cool!

Cool and unique concept. I think this a lot more potential to be a puzzle game. Making players figure out the right order of cards to win the match. It's interesting, haven't seen something like this before in my entire gaming experience. Well done!
BTW, what are those locked card slots for? Are they for future content? If so, good luck.

It's super cool that you have made a card game I think. The utilization of the theme is also great, it is a super interesting mechanic that the opponent plays your cards in reverse order. It really forces the player to think over their actions.

My experience is similar to what KorHosik describes below, more random cards would be awesome!

Very interesting game, well done :-D
