Thanks for all the great feedback from everyone.
To be honest I didn't even had the time to music until after the deadline. But I will keep working on the project just for practice. If I had the time on Sunday the plan was to add different dice (just your regular d4, d20 and such, but also maybe a d100 or more) ... but I spend half of my time on making a d6 work and even that resulted in rendering bug in the final WebGL build.
But I'm really glad about the nice word and will have a look at your games tonight.
