Since people have complained about the lack of the bombing tutorial again, I propose that in the selection screen where you cosmetically change your character and add a name, allow you to choose two weapons to take, the Proto Sword, Gun, and Bomb. The last one should be awarded after completing "The Ancient Generator", or "Should You Choose to Accept". This way, players are more aware of a bomb's existence in the first place, and might actually think about delving into a line of them.
