First, let me just say that I LOVE this game. I never played the original Yo Noid! game, but I do know what happens in it, and this is an incredibly fun fanmade sequel to it. It was giving me serious vibes of Playstation games, the kinds where there's a neutral "lobby" type of area that has portals that lead you to different levels, and you need to beat them all before advancing to the next stage (Spyro: Year of the Dragon and Pacman: 10th Anniversary are good examples), and that, coupled with the similar polygonal graphics, did give me some nostalgic feelings. The mechanics were also really clever, with the parkour that the Noid was able to do and using his yo-yo like Spiderman's webs, and even a final boss fight that only required the use of the yo-yo, without punching or shooting guns or other fighting mechanics ever showing up! Some of the exchanges between the Noid and the characters were also pretty funny, and I do love how there's extra Noids to unlock, giving this game lots of replay value.
However, that does lead me to the one problem I have with the game. As much as I love it, it's really annoying that I can't unlock all the characters. I can unlock Mr. Green and Cappy, but I can't unlock Fast, or, through that, Mikoid. I actually had this issue a long time ago, where Swing Factory wasn't giving me the PEPPERONI PASSION, whereas Plizz Anet and Domino Dungeon were. A month ago, I see that you said in this comments section that the version of Yo Noid! II that's available now should have that fixed, so I downloaded it and tried it out. In this new version, Plizz Anet and Swing Factory did give me the PEPPERONI PASSION, but now Domino Dungeon doesn't, once again preventing me from unlocking Fast. Is there some way you can fix this so that all three of the levels will give the PEPPERONI PASSION upon collecting all the pizzas? I got really frustrated (dare I say, annoid) trying to play the level over and over again, seeing if there was one pizza that I missed, only to realize that I was indeed getting all of them but the level just wasn't giving me the PEPPERONI PASSION. I really want to unlock Fast and I'm sure many others do as well, so, if possible, please fix the game so that Fast is unlockable.
All in all, I give this game a solid 9/10! I'd give it a 10/10 if all the characters were unlockable, so if that actually gets fixed in the future, then it'll raise my score to a perfect 10/10. But other than that, I really have no complaints with this game. It's funny, engaging, has good replay value, great mechanics, an early Playstation vibe that hits me with nostalgia, and even a catchy soundtrack! The first level (where the Noid needs to get his yo-yo again) has music and an environment that's an homage to the first Yo Noid! game, Plizz Anet has a bouncy and adventurous rhythm to its music, Swing Factory has a very jazzy and energetic theme (giving the "swing" in its title another meaning), Domino Dungeon has mysterious music very reminiscent of ancient Egypt, and the Noid Void and ??? have very eerie and unsettling music as well. This game has a lot more effort put into it than I thought it would, and I LOVE IT. It left me wanting more, and I do hope there's a sequel to this sequel. :)
