Okay this was SUCH a polished game. The art + music + sfx!!! A very very great job on this!
My feedback is that it'd be nice to have a difficulty level that lets players control the time limit. My first run through, I placed things at random and wasn't too sure about the mechanics. For this type of game, it'll cause you to lose since RNG plays a huge part in getting those cards that you need.
Again, very very amazing work!
