That's very nice of you to say! The tutorial is the weakest part, and one of the first things we're working on is getting more information to the player in a better way. For instance, the monsters will get "bored" and stop following you if they can't catch up, so instead of shooting every monster, the player should be looking to run away when possible. This makes it so the bullets are the player's "timer" for how long they can stay in the dungeon, and adds quite a bit of strategy to make them last. Of course, none of this is communicated effectively...
