Hmmmm, worked perfectly for me. Screenshots of doors completed linked.
Sorry dude, no idea. Had no issues at all, there is a lot of people saying about no touchscreen on the CM9 thread on slatedriod and I believe the only way to fix it is to do a livesuite image back. Or maybe using ADB you can reboot to recovery? Like I said, worked fine for me and I am guessing Matt as well as he was playing the game fine and got stuck.
Hopefully someone with a lot more knowledge will post up quick and help you resolve it.
