Great game!! the last 2 asked me to wake up this morning... but now I wish there was more hahaha! I want a puzzle that requires 6-7 cards to solve! :) Hit me up when it's polished, I wanna play it!
This has the potential to sell on steam with enough polish (the like of "Shenzen I/O" or "While true, learn")
You've got a great IP right there in your hands! I would contact a publisher if I were you ;)
