Hello there!
We are a team of professional developers, we draw and code for a living. We protect you from the common horrors of working with just a freelancer, like a sudden disappearance just before the deadline.
This is our portfolio:

Your project will be coded using mainstream coding languages, the engine of choice is Unity. Hence Cross-platform availability.
We want to start working with you right away and lead your project afterwards. "Batteries included".
You will receive a fully functional product by the end of the development process.
As we discuss the matter at hand, we will write, based on your description, a detailed estimate of time needed for this project.
Sincerely, Next Olive Team.
