I would call it more of a tech demo or proof of concept than a full game (and as metalcasket suggested, it would be perfect as a preinstalled game). I know that sounds like an insult, but it is a REALLY GOOD tech demo, etc. I imagine this was a monumental achievement to go from a Stugan project to realizing it to this point, and I in no way wish to diminish that, yet the consumer in me longs for more. I absolutely encourage people to buy it, as long as they understand what they are getting. Hopefully, many will and That will enable further development. There would seem to be a solid structure in place. What I don't want to hear is people griping about spending 3 bucks on something so short. It says right there in the app description that it is a short. It is also delightful and amazing. Glad I bought it.
