Hi,
I have been working as an Unity3D game developer for 3+ years and completed 20+ projects which are available on google play store and app store. I have already worked on games where I implemented AI-controlled enemy bots system, Drag and Drop mechanism, Inventory system and most importantly player character like you mentioned above. So, I think I am best fit for this work.
Waiting to hear from you and discuss more in details. Thank you.
