Undertale Yellow

• Play Undertale first.

• As in Undertale, the game really picks up around the middle. If you're not sold on it, try to make it through Snowdin before giving it up.

• The config menu has several accessibility features including Easy Mode. These features can be enabled and disabled whenever you open the game.

• Some of the boss's attack patterns in Vengeance/Kill Everyone assume you have fought the boss' pacifist or neutral variants. They're not impossible and it doesn't affect the story, but doing Vengeance first may be a challenge.

• In the Vengeance route, it is possible to hit an area's kill limit at a lower LV. This is bad for your stats, so try to aim for enemies that provide higher EXP. If you mess up, don't worry, it really isn't that much of a difference.

• Be careful on your Vengeance run in the

  ! Simply reaching
