Hello, thanks for your comment! I am really proud of how the pixel art looks even if it is inspired of existing resources (I took a lot of inspiration from F-Zero GP Legend vehicles for their sprites and GX character art for the headshots for instance) as I tried to replicate what would a F-Zero game on the GBC look like if it came out around 99/2000, hence the very F-Zero X inspired HUD.
As for the source code, I was thinking about that topic not too long ago actually ^^ I think I'll come back to it in the "near" future (if possible in a year or so to add some content) and I'll probably release the code then for people to see how poorly optimized this game is :D
