Wow! Really good presentation. I love the shading and the mesh of the die. The programmer art legs are actually really effective and adorable :3 Although this is the first D6 I've ever seen where you can roll a 9 lol.
The tutorialization is also really good (that's something I often have troubles with). But it turns into handholding when you specify what to do for every jump.
Honestly if you could give some context and give the player a goal to motivate them more this could be right up there on Steam. Great job!
