I love how paperclips is extremely addicting, but short. These games can eat up all your free time for months easily. Paperclips takes one day or two.

Spaceplan (http://jhollands.co.uk/spaceplan/) also ends after a while and was very entertaining for a clicker game. Apparently they have paid versions now too, which I haven't tried.

I paid for the mobile version, and it was easily worth it.

So it is a significant upgrade compared to the free prototype?

I don't know; I didn't play the free prototype, but I definitely felt like my money was well spent on the Android app.
