I finally got around to making a tutorial for this game. I covered a slightly different route "Bomb Room Route" than the one i use in my current Any% record. Its what i used when starting the game out because it provides for leeway in inventory management and doesn't require some more advanced tricks.

It is also useful for beating the game as well since the game kinda forces you to speedrun it in order to have a chance to get through some of the rooms.
