Thanks for the feedback!
We spent a decent bit of time trying to come up with an interesting game style that some of the common things got away from us till the last minute. As soon as we published we noticed the colors were WAY too similar for yellow and orange and we forgot to add the "in-game" rules and controls to our little KANBAN (oopsies).
Hadn't heard about the performance issues, yet, so we'll take a look at it and see if we can see what could be causing it.
Hope you had fun with our game, I def enjoyed what you did with yours!
