This is a really solid concept. I think it has quite a bit of room for growth; for example, why not have different elements of a room be impacted by different die (arrow traps, flowing water or wind speed). Each encounter could have unique things that are rolled for!

Nothing like rolling 3 consecutive 1, eh?  Good enemy diversity, and I like the environment drop interactions as well.

Entering the third room. Self rolling, 2 & 1 & 1. Enemy 6, & 5 & 6. Environment 2 & 5 & 6. Died almost immediately. Exactly Classic D&D experiences! Anyway, great game, very fun, simple and cool especially when dice roll with slow down John Wick motion experience! When you get 6 it is fun but when you get 1, you tries to find reroll. The bomb can be surprising not knowing where it will spawn but overall, very fast-paced and fun!
