Underhero is a RPG. There is (bad) 2D platforming and an interesting blend between turn based and real time battles with decent amount of player expression, but I find most interesting the writing and scenarios you will find yourself in during the game. You play as an Underling after the Hero has an unfortunate accident after all, and while technically a silent protagonist, all entries in the journal/hint system/to-do list are just brimming with personality.
I swear I first saw this game in list of “Paper Mario-likes”, but I can’t find a single video with that topic that mentions it, and now I realize that it only has like 600 reviews on steam.
