I just played through the new demo and enjoyed the gameplay and the scenes. You can tell that DO! puts a lot of love and effort into this game.
I found only two glitches so far one being that the gamma access code doesn't allow for you to interact with the gamma npc's for their scenes, and the other being at the RGB forest after you recover blinky if you continue to explore the area and leave the boss room you'll get stuck in the wall above the staircase.
