This was exactly what I was looking for. Love this style of pixel art and it works perfectly with GB Studio. The reference page helps a lot. I see that the Ninja mode is coming soon and I'm looking forward to that. Couldn't wait so I bought the other pack to tide me over until then. I've always wanted to make a GB Studio game but could never find the right assets. If you make any more content (Maps, Tilesets, etc) I'll probably be your first customer.
