Nice Gameboy style Metrovania. Gameplay is simple and intuitive. You never change weapons or equipment, but find other characters you can switch to, each having their own abilities and challenges.
A few things I'd like a little different, mostly around the map: I wish the map better recorded things like doorways, statues, and prisoners. It was kind of hard to go back and get another character and then try to remember what I was doing, especially if I'm not playing the game all in one go. Also, if the game respawns all monsters when I enter a room, it shouldn't respawn any so close to the door. In a few places it is almost impossible to enter a room without getting hit because the monster spawns right there in front of the doorway.
Those are just minor things, overall the game is very playable and very enjoyable. Thank you for writing and posting.
