I love the look of the emril pickaxe but if you could make it so that if ur holding a pick its in your hand but if your not holding it its holstered on a belt and visible that would be cool and a nice attention to detail :)
Oh and making coal appear a bit more often would be great. Awesome game great work, definitely a 10/10 game when it comes to graphics and when its done, 10/10 in all aspects :D
