Hey thanks for playing and for your helpful feedback!
The usage of a symbol multiple times is a bug indeed and we actually found out about it after we submitted the game, but the fact that you discovered it wow'd me xD That means you played a lot! We will fix this in the post-jam version among some other things to try balance the game the better way possible. Your input about the used die is pretty important too so we will definitely look into it!
We are glad you enjoyed our game, thank again!
