For the tutorial, it was not clear that the shape of the level was to tell you to use the "R" key, I only figured it out after accidentally pressing R and getting somewhere in the level. This could easily be fixed by actual text instead of using the terrain. While the weight of the die to affect stuff is cool, the randomness of the roll makes it frustrating, especially when it was difficult to get the die into the needed spot, just to have to do it again because the die wasn't the right weight
