Hello.
I see you want to build a simple game which is addictive to users.
I've 6 years experience in game development by using Unity3D, Cocos2d-x, HTML5, Libgdx, etc.
For over last 6 years, I've built many games including 3Match Game, ETJump Style Game, Subway Runner, Poker, etc.
By the way, I've few questions about the project details.
1. Will you provide design?
2. Do you want to run it on Android or iOS, both?
3. Is there any similar app?
4. What is the timeline?
As you see on my profile, I've rich experience in game development and have many projects done.
I am available full-time to work and will fit your business time.
Thanks, and look forward to working with you soon.
