I'm so glad to hear that! I originally started developing Tiny Dino because I couldn't find a virtual pet that I enjoyed. So I chose to make it myself!
The price won't be changing. Once the game is close enough to completion I'll be releasing it on steam, which will allow me the ability to localize the price for different regions. I want to make sure my games can reach as large an audience as possible, so keeping the price affordable is one of my top goals.
Although, I will probably be putting Tiny Dino on sale for a short time when the new version releases. So keep an eye out for that one.
