Develop a Simple 2D Web Game

I'm seeking a skilled game developer to help me create a simple, 2D, web-based game inspired by MapleStory. The game will feature very simple platforming and combat mechanics (much like MapleStory, but with only one type of skill). I can provide the necessary visual assets, so the focus will primarily be on implementing the gameplay and customization systems.

Ideal Candidate:
- Proficient in game development, particularly with 2D web games
- Experience with platforming and combat mechanics
- Can work with provided visual assets
- Creative input on gameplay and mechanics is welcome
