About the Game
DELTARUNE is a chapter-based bullet-dodging RPG that runs parallel to UNDERTALE's story.
DELTARUNE is an independent role-playing game from developer and publisher tobyfox, and it sits in the same universe as UNDERTALE. The store lists it under Indie and Role-Playing, and the description calls it the next adventure in the UNDERTALE series, told as a parallel story rather than a direct continuation. You play alone, and the game follows a linear, chapter-based structure that the store page says you can pick up from anywhere.
The core loop is exploration followed by battles. You move through a mysterious world, meet new characters alongside familiar faces such as Toriel and Sans, and then reach encounters where you can either fight or spare your opponents. Battles are described as creative bullet-dodging fights inspired by games like Touhou and Chrono Trigger, so you spend the fights moving and reading attack patterns rather than just picking menu options. The store page also mentions hidden bosses that are described as jevilishly difficult, which suggests optional challenges for players who want more than the main path.
What stands out is the presentation. The soundtrack and story were written by Toby Fox, and the store page describes the soundtrack as massive. The pixel animation is credited to Temmie, and the description promises smooth, expressive character movement. Chapters 1 through 5 are listed as available now, and the short summary notes that more chapters are planned as free updates.
The store copy also says Chapters 1 and 2 can be tried for free and that further chapters must be bought, which sits alongside the summary's note about future free updates. Because the two statements differ, it is worth checking the official Steam page for the current arrangement before you commit.

Who It Is (and Is Not) For
Recommended For
Players who enjoyed UNDERTALE or want to revisit its characters in a parallel story will find plenty to recognize and enjoy. Fans of bullet-hell style combat will appreciate the battles, which reward careful dodging and thoughtful choices about when to fight and when to spare. Controller players also get a comfortable setup, since full controller support is listed.
Not Recommended For
Players who need Traditional Chinese text should look elsewhere, because the game only supports English and Japanese. Anyone expecting a fully free game should also be cautious, since the store copy says only the first two chapters are free to try. Players who prefer open-world exploration or who dislike precise dodging may find the linear, bullet-dodging structure less appealing.
What the Steam Reviews Say
Steam rates DELTARUNE Overwhelmingly Positive, which is 壓倒性好評 in Taiwan Steam wording. Its 98 percent positive score comes from hundreds of thousands of reviews, which places it at the top tier of Steam's label scale and means the great majority of players who reviewed it recommend it.
A score like this is considerably more reliable than one built on a small number of reviews, because a large sample smooths out the opinions of a few unusual players. Steam labels are calculated from the share and volume of positive reviews, so a high percentage paired with a large count is a strong signal. Even so, reviews reflect the experiences of people who chose to write one, so you should read the score as a strong general indication rather than a promise that the game will suit your own taste.
