ROLL.EXE ACTIVATE! :D Aaaaaand she's gone inside.
This was a very delightful tunnel ride. The pacing akin to a sugar rush didn't exactly lead itself to scariness, and I experienced mood whiplash more than once, but it was overall fun. Also, the art makes great use of colour and the writing is funny. Good use of the transform properties with the sprites!
Personal pet peeve: I'm not a fan of the UNDERTALE style of talking voice SFXs (especially since all the characters have the same) but I won't count it against the game.
Also, full marks for the Visuals just because that CG of the G**** in the m***** got me. I don't know why, I was just '*gulp* okay, that's creepy*'. Writing wise, though, there's a few things that I couldn't really grasp. I guess it's because this is a spin-off of another game but they weren't properly re-introduced in this.
