Thanks for playing!
The RNG is a fair criticism... in the original idea, there was a mechanism for the player to reroll their dice. The thinking was that the player would have a limited number of chances to mitigate their bad luck., and they could earn more chances by doing something impressive (e.g. clearing the entire board, clearing a row and column at the same time, etc). Unfortunately, it got cut from the scope in order to meet the deadline!
