Frikin awesome, like wow. They should pay you for it lol.
Is there a way to in the skills description to explain what some of the skills will actually give you, like crafting level 1 will let you make such and such?
Actually really the crafting stuff is the only ones that are very limited in what they will give you.
Also I know it might be a bit of work, but maybe in the future as you develope this thing, it could have a level button we click that will only show the skills available at that level and the cubits that are earned up to that level and avail points to the level to spend.
