Glad you like the concept! It felt very appropriate to have the die literally be the boulder. Not convinced the odds of winning are quite as good as you think they are though...
Entirely possible I did the math wrong. It's been a long time since I took statistics.
(1 x .95 x.9 ... x .1 x .05) was my guess which comes out to 2 millionths or so.
Oh, I meant that the final step is literally impossible, you can't roll a 21 on a d20!
Ohhhhh... I misread it. For some reason I thought that if you rolled a perfect 20 on the last step you were free. My bad.
Actually, no, your bad. This is a game breaking bug and I insist you fix it immediately! Lol
I suspect it might be a combination of both of us on this one! Not sure if my writing was the most clear on the roll needed for each step.
