Really great game! I'll admit I was frustrated into almost quitting at first, but I'm glad I stuck with it. Runs where the luck just doesn't go your way were frustrating, but it just makes getting on a good run that much more tense. The ability to control your randomness via rerolling and replacing faces of your dice gives the game a different kind of strategy, more about hedging your bets than devising the perfect plan. I also really like how you could abuse encounters to farm health if you knew what you were doing.
I will admit that I was only able to beat the game by abusing what I assume was a bug where you could reroll your number by pressing the button really quickly after the initial roll before it switches to the other die. However, I actually really like the bug and think it would make a good mechanic; it forces your to make a split second decision about whether the number is good enough, and you can potentially screw yourself over by getting a lower number.
Also, for those curious, my final winning loadout was two defends, one attack, one attack all, one double attack, and the shield which gives you +3 to your defend rolls (no sword upgrades used)
