Quit unexpectedly all the time

I downloaded the ios version, it is really a GREAT game. :) That’s the reason I want to download it on the Mac. BUT, I cannot open this game, (perhaps because I am the new version of Mac?) I visited the Blocks Support. "Support is available during regular business hours (Eastern Standard Time), and usually takes less than 48hrs for a response.” (copied from the website). However, it has been 2 weeks and I havn’t reveive any responses since I submited my request. :(

ooommmmgg about Blokus™, v1.0.0
