I used the metroidvania genre mostly because parts of the map are inaccesable without the use of certain characters. You can't go over pits with the kid, but the ninja can and one wall can be removed only by a certain character. It isn't like other metroidvanias where it's a giant map, but that's because of the time limitation. I do agree that some enemies in some rooms are too though and I will change the description of the game page to make it clear you can pick the caps you collect by going to certain rooms on the map at the start of the game to change your character.
