I think this version has no big problems like the previous one in regards to the setups before the last section. The way the geysers work is demonstrated extensively, both in terms of player movement and NPC interactions. The visuals, as well, look incredibly nice. The bonus underground and custom cutscene is something out of the blue, but I suppose it is a nice reward for entering the vase. I think the problem is with the 3rd Star Coin, which is slow to get the correct angle for the shots, but fun regardless and pairs well with the properties of the geysers.
Regarding the first Star Coin, I am no intellectual. It took me a while to realize to
lure the rat from the generator to the sand pit right after it.
I think the hint is a bit better in conveying the message.
I think the electric section is quite overwhelming. While there is a lot of variety with the setups, it is rather long and warrants an additional powerup/fix somewhere before the ride. The ride setups are jank, and you can easily die to the one without the quicksand. And somehow, you can create a loop of electric shock on the first layer if you jump at a particular time. Nonetheless, I don't know how to fix the section to make it look natural as a desert cave. The purple gets in the way of the yellow and orange, and it feels odd.
Aside from the bugs, you have to fix, there isn't much else that I think is problematic. Maybe except for the PNPC warning that pops up since it is a technical problem and may get your score deduced.
