These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: ALLTYNEX Second
Game Breaker: The mech's swords are ridiculously strong, don't drain energy, and can kill most bosses in under ten seconds. This is offset by the fact that you have to be right up in the boss's face to hit it, and the boss isn't going to just let you waltz right up to it. The scoring system encourages you to switch between the swords and shots by awarding Combo bonuses for using the shot instead, particularly on weaker enemies.
