Concept is cute and simple. A lot of work into the menu and the friendly tutorial.
I used a freeze card on my oponent early and he didn't unfreeze. Repeated that. Yep. Freezes untill the end of the round.
Hard to read the cards since it needs to be done quick. Effect cards could use icons or pictograms to improve readability speed.
Didn't understand the steam mechanic, since it lowers the score it seems really unproductive to use. If you behind and you use it you might fall more behind. If you're ahead. There's really no benefit because of the -3
Also 1/5 pulls are 3 empty cards. Maybe empty cards should be small +score instead. Holding 12 second combo to receive nothing is weird.
But else would love to check it out more.
