I LOVED Nya-Nya XD Best mascot ever...and the story was lighthearted at times, and serious at others. This was fun ^^ I can't wait for the full version now!

I also made a let's play. Hope it helps!

This...this...is awesome. I'm unsure why. It's got such a unique art style, and that "This is the story, but believe me, even we don't think it's very believable but it's what's happening right now so shut up" vibe that I absolutely love.

I haven't completed it yet (And I know this is a demo, so I haven't even completed the demo), but I can't wait to see what else happens! I'm an Otaku, so this game resonates within me like justice within a Magical Warrior of Peace Love and Happiness.

Also, I love Visual Novels, so points. Thanks so much for making this!

Aw, thank you!!! I'm really glad to hear that you like my art and writing! <3

Those were the exact sorts of vibes I was going for with this game~

And thanks for the LP too!!

I really enjoyed this game!! :D Not that often that I play Visual Novels on the channel but this one was really good and cute! Kinda reminded me of Sailor Moon :3 Full Playthrough right here! (Is there different endings?)

Stay Rad Everybody!!

Wow, thank you so much!!!! I'm so honored you did an LP of my game ๐Ÿ’–๐Ÿ’–๐Ÿ’–๐Ÿ’–

There were meant to be different endings in the final game, but due to time constraints I could only get one route done. If I ever pick up this project again, I'll probably add those endings, amongst other things
