Go here from your phones browser and click the link for non market install. It will be a mediafire or rapidshare download of the apk. Installed just fine for me and have not had any FC's or freezing yet.
this beta doesnt like the EVO very much. I read on some site the developer is working on it.. however..
it will run in it's current form.
try this.. after the launch screen and during the loading screen.. run your finger around for the duration.. circles.. figures 8's... whatever you want. just keep some chill motion. I saw that tip after a google search and it worked for me.
I run an unchanged EVO on 2.2 froyo from sprint/htc.. not rooted or anything.
As for the game.. fun
Oh I also read that if you mute the sound when you close it.. it will relaunch just fine.. however I didnt get to test this as my one seassion with the game was at work and I had something pull me from my session without trying it. I will next time I try unless someone else reports it first.
