Hm, not so random it seems
I think i sense, as an attempt to add difficulty into the game, you gave the opponent a much higher chance of rolling a 6 or 5 than you. Just an observation when your rolling 4 dice and they roll 3 and they keep getting a 6 or 5 on at LEAST 2 of the 3 dice every roll and you roll 1-4 on each of your 4.
Dumb altered chances aside, The classes were stupid. the game wouldnt have been possible without Mend or the Heal class
Each fight: put mend on one dice and just click the Roll button over and over until you win= beaten game. Even then you will end up with 15-25 HP left. (after Mend retrieved at least 75-100 HP for you by the end of the game) heal also will get you an extra 25 hp early game before you get mend.
