I like the concept of the game, and it's a good time killer.

But I had some issues when starting out. Mainly being that the Jack card was said to be a wild card, but I could find no use or how to properly use it as a wild card. And at first I didn't know that the bad meter could decrease with each successful pair so it felt like I was very out of control for the first few rounds.

Adding more clarity on the mechanics and a difficulty setting for card speed or card columns would be nice.

Good pixel art presentation and a relaxing song. The difficulty level is a bit to high. Might try to adjust the difficulty level from relax and slow pace to gradually increase the level up until this current one. 

Tried the game.

This game can really benefit from a difficulty slider or modes, so people can reduce or increment the amount of cards on screen. Maybe even editing the speed.

It’s a game which does it’s job and a good entry, the trick of mixing cards is always fun and the fact requirements changed during the game make the game more chaotic and fun. Congratulations!
