grid based movement, turn based combat, strategic play, procedurally generated levels, exploration based discovery, run based playthroughs, single character, new character per run.
Roguelike is more apt than any other description.
a dungeon crawler, gridder, blobber, and so on usually have static maps with puzzles, party management, real time movement of enemies, real time combat, and don't normally fit the roguelike description. calling this a dungeon crawler because of the camera orientation is a disservice to roguelikes and dungeon crawlers. This is definitely a roguelike first and dungeon crawler distant second.
Keep up the awesome sauce, this is a real gem!
