Thank you for playing this and also the old BRU ! The plan is indeed to allow for player customization. This program (Random Toa Generator) worked well for random input, but was not optimized at all for custom editing (yeah, I rework the logic often and it gets sharper every time)
You should have some news from me on my twitter when the customization is done.
The prototype masks are based on Rothanak's, with some modifications so they can fit in game.
