Hey! Glad to hear from you again!
First of all, thanks for the video :)
I agree, we need something to make next runs more fun, and as you said a shop with some kind of currency you earn on the dungeon could do it, we will explore that possibility!
Also since I saw you talking about it on the video, your natural 20 does count as critical, we just forgot to add some visual feedback for it! And for your damage rolls, they are rolled depending on the weapon you've equipped (for example, the rapier you did so well with is 1d10). We didn't want to fill the screen with rolls and try to keep the combat fast and simple. I can understand the confusion though, we might have to think some way to better communicate the damage rolls.
Thanks for the feedback!
