I really enjoy the co-op aspect of this game. VERY fun. I was also impressed with the accuracy of the access point "star" throwing. Throwing is usually off on WMR devices, but it worked fine.
My only real gripe was after completing the mainframe hack. It was immediately obvious what needed to be done, and I only have a few seconds before being spotted and losing the game. This was the first time there was no "countdown" to the amount of time you were truly "spotted". It was pretty frustrating to get that far only to be confused as to what to do, fail, then get sent ALL the way back to the beginning. At most, the player should be sent back maybe one room.
Beyond that one complaint, I think it's a great game and should definitely be fully developed and released on Steam. I'd pay for it.
