Really great fangame, clearly a lot of dedicated people worked on this and I'm glad it finally came out.

Music and spriting are both phenomenal, dialogue and story are mostly good but there's some points that I think were a miss. A lot of the story/character stuff is also heavily loaded into the second half of the game, I think they could've expanded on the ruins section with Dalv and that would have helped a lot. Some of the enemy bullet patterns have difficulty that's all over the place too, I think some of the bosses were really good but some of them definitely needed some improvements. Overall a good time if you're a fan of Undertale.
