Hey, nice to see this art gallery come back! Overall this is a pretty dang cool and creative art collab and I really enjoy the 3D gallery concept as it is a breath of fresh air compared to typical slideshows!
Loved the little scanner device you have that allows you to get details about artwork and even link to the artist's page: very nice quality of life! I will admit, though, that I'd kind of prefer if the scanner blanked out when you're not looking at an art piece instead of freezing with the last seen one: that's just my preference, however. I also found it disappointing that there were a lot of artwork like decals and characters that I wanted info, but the scanner doesn't give anything for them: oh well!
I have to admit, that as cool as the gallery is, I was getting a bit exhausted of it halfway through: it just felt like so many of the rooms were the same bland purple-blocked rooms over and over with the same music playing the whole time. Would much prefer if there were a higher quantity of rooms (or at least rearrange the architecture to better pace the journey) having cool and unique themes, construction, and music to them, like the COD Zombies room, for example. It was also a bit strange to see so much reused stuff from the previous collab. I also felt like maybe there were less easter eggs? Or maybe they're just hidden too well, haha. Anyway, the combination of these factors made me feel like this gallery was a bit less well-developed, even though it is still nice in a vacuum. I guess you raised the bar so high I couldn't help but want more from ya!
