The "time boxing" is coming to be one of my favorite aspects of the roguelite genre. It's a nice structure for a combination of a deep and compelling game, that opens up at a reasonable speed, but also doesn't call for 80 hours to "finish" it. I like JRPGs but even so they quite often overstay their welcome. Death may wipe nearly all your progress but you can easily try again in another timebox.

(I played some of the classic Roguelikes, and spent a lot of time with Angband, but that was one of their problems... winning still took many hours, could easily be dozens, and so death became very scary. They were on to something, but the modern rebalancing of "hand it all out more quickly, and resolve the game in an hour or two and let them come back" seems a much more practical approach in a lot of ways.)
