“Very good. Well written. Definitely enjoyed. Got it for the cute blue guy on the tin. :D I haven't finished with all the achievements yet but that's my plan. Definitely recommended if you like these kinds of stories.”

“It is what it says on the tin. Voice acting is great, story isn't deep but still quite structured and layered. Art is awesome. You'll definitely enjoy :)”
