This is what I shared on Twitter a few days ago.
Since this was recorded through the Switch, though, you can’t really see when the burn-in protection triggers. So here’s a video of the bug but recorded through a capture card, where you can clearly see (and more easily hear) the glitch that I’m talking about.
The glitch was partially fixed on the current version which was released recently (October 10, 2018). There’s still some sound distortion but it’s now very hard to notice it.
Got the demo of PixelJunk Monsters 2 on Nintendo Switch a while ago. Downloaded it through the Japanese eShop since it wasn’t available yet on any other region. (I think it is now available now, btw)
Anyway, the point of this post is just to share a few glitches that I experienced while playing it, and maybe the reason why this demo wasn’t available outside of Japan yet. (or maybe the glitches are still there, XD ) (Update on this situation below)
The demo is supposed to have English support and I was playing with my Switch set to English during the whole time.
Suddenly, all these menus became in Japanese while I was playing.
While using both joycons as one controller, everything seemed fine…
…but then I switched to single joycon and the Switch suddenly has L1 and R1 buttons? XD (A leftover from the PS4 version.)
Whatever you used as controller for P2, it always showed the right joycon.
UPDATE: A few minutes after this post was published, I got a reply on Twitter that confirms that these glitches do not exist anymore in the full version of the game.
I can also confirm that the software in the demo version that is accessible through the American eShop is the same as the Japanese one, even though the ID seems to be different. (So you can essentially have the demo two times in case you want to do that by some reason.) The glitches still work in this version (demo v 1.0) in case you want to check them out.
