Hi,
I've been using the Unity engine for over 2 years and have experience with gameplay programming, UI, inputs, shaders, implementing plugins, data serialization and more. I worked on a match-3 type game that can be seen in my freelancer portfolio. I'm currently working on a 3d jrpg style game, I can send you some samples if you contact me.
This sounds like an interesting project, I'd like to know more. I'm not sure if you are looking for just a programmer or if you also need an artist. I'm not an artist but I have a coworker that would do the work if, that is what you need.
I'd like to discuss the scope of the project further: what you currently have and what is the final result you are looking for. Once I know more details, I'll be able to update the bid and timeline.
Thank you for your consideration,
Martin
