Interesting idea getting your arsenal of dice + luck set up in order to make it deep into the doubling process. I feel like the early game is a bit unfair as there is very little you can do to prevent bad rolls and any loss in HP early on takes away a lot of wiggle room in the middle game. Once you're stabilized, however, it feels like the player has a lot more agency. I found that I was way too reliant on just the luck and dice stats and that I needed to pad my life a little more often to guard against a random debuff.
Good stuff! I also can't help but notice that submission time; congrats for making it in. I also submitted with <10 minutes to spare for the "risk it for the biscuit" metagame.
