Thanks for your reply!
I am actually planning on developing this further after the jam ends. There were features I didn't have time to include, and now there are even more ideas for this game.
Physics must be fastened. Another way to do it is to copy the dice and throw multiple copies of it simultaneously, then read value from each one (same thing you do irl in a big board game to roll many numbers at once). More levels are also required.
Whoever is interested, stay tuned for the future of this game. I still can't guarantee I'll do it, but I'll try :) And thanks again for your reply, it really helps me stay motivated and enjoy this jam!
