I just finished my first Adventure! One page games are a bit tough for me, but it went rather smoothly for me. I may start a second Adventure with my PC, Yorik Tienk, later!
I rolled 2D6 (rerolling 1's) for each room's length and width
That looks awesome! So glad things went well for you. Love your solution to determine room dimensions. I'd be very interested in hearing how more of your adventures go :)
