Oh wow, what a great entry, this completely went under my radar.
Excellent interpretation of the theme. Having to play against a cheater is already an interesting premise but changing the rules after each call-out is really going the extra mile, I love this. Altough I would have loved being able to choose which game to play first. Having to go through Tic-tac-toe and rummy before getting to UNO is a bit of a bother on repeat playthrough. Especially since Tic-tac-toe can be won the same way every time and her alteration to the rule doesn't change that much there.
Visual are a bit prototype-y but still pleasant. Your host is the highlight of the game, nice variety of facial emotion, she's full of personality. Your cards and tic-tac-toe boards could be better looking, but then again, we only had one week. I'm impressed enough that you've managed to cram three whole games into this. Amazing job.
Great score all around, congratulation.
