Awesome! Totally captures look and feel of the game. Although a few more stone and grass vartiation tiles would greatly improve the look.
Really clean and lovely mockup, I just had a hard time finding and distincting the player character.. Might have to do with this being a still shot and if it were a real game with the character moving it might not be that big of a issue.
A mockup so good it could be an official GBA spinoff. Excellent work!
You are great.
