Hmmmmm...this ones practically as tricky to judge as solving the puzzles within!
On one hand, I feel like the game is generally very well constructed and has a great level of polish to it: everything looks and feels not just good, but very stylish as well. I love the whole picture book presentation and gameplay graphics as they are very charming, and the puzzles are quite the brain-teasers! I'm so used to puzzle games starting out slow with tons of plodding tutorial-esque levels to get you used to everything, meanwhile this game is almost refreshingly starting off strong with some very elaborate puzzles right at the start! Seriously, some of the first level puzzles were absolutely crazy and unique, even making you go back to past puzzles with future pieces to rearrange them in new ways to progress: this type of design where puzzles spill over into each other is wild! Later levels introduce even more interesting mechanics like the gun and it just keeps going, and I do think the game tries to teach you mechanics well in subtle ways, like how you can see the entire island glow when it gets charged to let you know that any bridge blocks that get placed on the island will also get powered: seriously impressive stuff!
I gotta admit, however, that as much as I like a challenge, I feel like this game overdid it and I could've used a bit more of a slower start and some tutorials/explanations as my peanut brain was struggling to even get past the very first level! Some of the solutions just seemed plain ass-backwards strange at times: I solved the final puzzle in the first world by pushing a battery onto a previous puzzle island, resetting it to delete it from the board, and then with that obstacle removed I had enough room to move around the final pieces to get to the end: I'd like to say it's intentionally clever, but it feels more like I broke/cheated the game and with puzzles this wild, I really have no idea what's the actual case!
Also, as a small petty complaint, I just kinda feel like this game isn't very Pico-ish: feels like you just had a puzzle game being built and just slapped Pico on as a shallow cosmetic skin as an afterthought to make it work for Pico Day, rather than creating an actual Pico game from the very start. I mean, c'mon, light-bridges? Batteries? In what world does this make you think of Pico? But whatever, it's not that big an issue.
As stated, it's very tricky to judge: while I did enjoy the eureka moments I finally had where I figured out some wild solution to the really complicated puzzles in this that refuse to teach you anything, I also found myself quitting several times out of sheer confusion and exhaustion (but again, the game was interesting enough to have me come back a few times to give it another go, so I dunno whether that's good or bad!) In this case, I'll give it the benefit of the doubt with a decent score since I think there's stuff to love here for the smarties in the audience, but woof, I dunno!
