Twins of the Sun

You can certainly see some variety in locales and enemy design but the combat becomes very stale. Twins of the Sun's loose melee swings don't really pack a punch. It's not a difficult game but certainly feels better playing as a duo. The wave-based encounters draw a lot of attention to those flying solo, even if the game is very lenient with health pick-ups. This is competent but it lacks a tighter feel.
