1. the Initial hurdle of what the icons are and do (It's actually fine, I'm not gonna harp on it)
2. I think... THIS HAS BEEN MY FAVORITE SUBMISSION SO FAR, Great use of theme, Tower Defense as a genre is already a +1 for me and a polished one at that, the RNG of what towers that you get is a great/innovative mechanic, having 2 different tables you can roll on really adds to what I like with this premise (In a expanded version, I think having more of these would be great).
3. Your team really showed out be proud of what you put out, the music is great and creates an atmosphere of being in the casino, the art is well thought out and is the biggest help when trying to convey what each of the icons do.
