I'll be sending out the instructions and game later tonight! If you haven't gotten an email back, you're on the list and will be getting a copy of the beta tonight.
Assuming that you were already a skilled gamer, that was about the minimum completion time we were shooting for. For most people that we had try it, it took them closer to an hour to beat. We also have some ideas for extra levels to add in an update, but felt that the current set of levels was enough for the initial release. The question is, can you beat them all with gold medals in 30 minutes.
Getting gold medals on all the levels will probably take me a couple of hours, so there is definitely a good amount of content there. I'll send you some feedback via email either today or tomorrow.
We've had some fantastic feedback so far, we're really glad everyone is liking the visuals and gameplay. It sounds like there haven't been any levels that really stuck out as too hard for *everyone*, and it sounds like the challenge level should be pretty good for the casual gamer! All the emails have gone out now, so if you haven't heard back from us, you weren't selected for this round of our beta program. Very sorry, but keep us in mind for next time! Edit: Jason, yup, we got your email! Thanks for the fantastic detailed feedback. (and regarding your request for an easter egg.... "Go for the gold" means getting a gold on every level, but let's not spoil the surprise until the official release)
