Hi there,

I've checked out the game and I see what you need done.
Contact me on mungodwib@gmail.com if you need to.
Portofolio:

or

The assets should only take half a day to finish.
I do both pixel and vector art along with concept art and illustration.
Price depends on what budget you are working.
