Room transitions are bugged, I'd walk out of a room and come back to a different one, I only noticed that because of the room labels in the corner of the screen, otherwise I don't think I would have noticed since the rooms I've been to were mostly very similar, with the exception of the background and the layout. It's a shame that there's a bug this bad, since being able to traverse the map is probably the most important thing in a metroidvania, but I think that if this was fixed you could have a cool game with solid combat.
