Hi there, I just purchased this Tileset and it looks really cool :D You added pretty neat stuff... I was trying to make something with your free tileset, and ended up also adding some more stuff for the player, coin and water animations and also extended the grassland tileset adding destruct block and grass on the sides. I'm definitely not and artist, but if you want I can share it with you.
Ill try to show some kind of a playable prototype in the near future :+1
