Well,
it's good conceptually, but I think you should be able to kill the guards. Not to mention be able to leave the area if you are in alert mode. It's also a little awkward to have only left-handed directions, an asdw motion addition would be nice with the abilities moved to two of the right hand buttons. Overall, not bad, but if you think ahead a little more I see great games in the future. I'll be waiting for that sequel.
