Well, there go all my achievements as I reload again... 😞
Yeah, and I had it happen again just now—the third time so far. I've been playing for a month or two and every now and then when the game starts it spawns a map with just the dungeon entrance and no way to get to any other rooms (since I don't have a dynamite bomb), even when I can tell there's another room there (e.g., looks like there's probably a library [?] just north next to the player token from the carpet color under the wall tile). Randomly-generated maps are great (seriously! I'm really loving this game!!) except for when they're not!
This was another fun one (I didn't have a dynamite bomb at the time, so I never found out what was in that locked room...the level spawned just like this with no key in sight 😅)
Ah damn, it's a glitch in my random map generation algorithm. I did remember it should normally check any generated map for a path between the starting point and the exit, and discard the map if it's invalid. Normally this was tried 10 times before failing, but the generator was good enough that I never witnessed three failing tries in a row, so the 10 times was normally perfectly fine.
Sorry :-)
