Huge exploit with Dwarf Knights. You can train endlessly with them for higher and higher stats.
Albyon is an overground rogue-like, that will eventually become narrative-based, somewhat akin to interactive fiction. At the moment it is still in early development, so very little of this is evident.
It was originally my entry for the RemakeJam (June 19 2017 - June 26 2017), and is rather distantly based on an rpg that I wrote on the ZX Spectrum back in the 1980s. It was essentially an overground rogue-like, although that term didn't exist when I wrote the original, and at the time I hadn't come across NetHack or indeed any other rogue-like. It was a sandbox game, with no specific goal other than to collect wealth and fame, at least as far as I remember.
