For a game that's unbelievably janky, I really enjoyed it. The whole ending section that reminded me more of weird games like Pathologic than a JRPG was pretty neat, especially for a game from 1989 that barely even had a story. The three different progression systems (mutants use a more standard SaGa system of gaining stats after each battle, humans need to get stronger through the use of consumable items, and monsters eat the meat of fallen enemies to morph into another monster) were kind of cool but expectedly really basic. I didn't like how every weapon was consumable, but other than that I didn't really have any mechanical issues with it outside of the expected jank of an old Game Boy JRPG.
