Itās a really interesting puzzle!
In my opinion the symbols are easy to understand, but itās cool that you have a hint system that explains them in plain text. But it may be a good idea to show the names of the tribes even with hints disabled.
The art and animations are also great. I donāt really like that there are 2 tribes that are quite similarly red. When going fast I had troubles distinguishing them, and maybe some variation in brightness between the two could help.
Oh, and I thing you missed a cool idea of making you drag the guys onto the button play to start playing. All in all, good job!
