Reviews
gameplay very fun, more than undertale music peak writing is good for all chapter so far except ch5, it wasn't epic i like it because the main characters are full personality and feel real, it's as if they are my friends the mystery is very intriguing too good because it's not finished yet, so i can keep theorizing about what will happen next.
伟大无需多言,建议速速更新
my save file, funnypoos, has become... controversial.
I've loved this franchise for a while now, though I'm just gonna talk about ch5 now. Potential spoilers I absolutely love chapter 5, it must be my favorite one so far. Love the vibe, how similar it feels to chapter 1 in some ways. I adore the music and aesthetic and how Japanese inspired it is ♥ And I also loove the characters, esp. Mew Mew and the flowers based on the 7 souls of Undertale (Aqua is just the cutest). This chapter also feels like we're really getting somewhere since we can see Asgore and learn that he'd been delving in all the stuff for a long time already. I'm curious if any future chapter can beat this one for me, but even if they do, this one holds a special place in my heart, hehe ♥
Good :D
