World of Goo 2 is another sequel to a game that I don't think needed one. However, given the amount of time since the original, I'll let this one slide. I haven't played through the original for several years, so any references to it are from my own memory, and may not be accurate.

I remember that there were several types of goo in the first game. This game introduces a few types of goo that interact with oil. I'm not 100% sure that it's oil, but it's a black liquid that comes out of the ground. There's pipe goos, which suck up the oil and transport it through other pipe goos. There's expanding and contracting goos (the latter are sparingly used in only one chapter). Pipe goos can also transport oil to sprayers or engines, and another kind that condenses the oil into proto-goo balls that can't be built with.

Gameplay involves building bridges, towers, and other structures to transport your goo balls to a pipe. Along the way, there will be obstacles. Like the original, levels will often feature an infinite gap somewhere. Sometimes water kills your goo balls, sometimes it doesn't, and I can't tell which before diving in. Many levels, particularly towards the middle, have lava. I hate it. It destroys everything that touches it, and there's sometimes a fountain of it that explodes near the end of the level just as you get there.

While undoing a move is the same (finding and clicking a fly), there's only one of them. In the original, there were several that buzzed around, but each was one use only. Here, you can undo an unlimited number of times. In the original, clicking on nothing made a chirping bird sound that made goos move faster and towards the sound. Here, there is no such feature. Goos tend to congregate near where you're building, so if you start building on the other side of the level, it might take some time for them to head over there.

There was one chapter that is set on a relativistic train. When it crashed, the game got a severe but entertaining case of sequelitis. This came in several forms, all of them were wild dreams of where future World Of Goo games could go. This is where I started loving this game. One moment I was playing a synthwave World of Goo, the next I was in a pixelated film noir point and click adventure game. Maybe this was a commentary on game sequels, but I'm not sure what the point was. The whole chapter is a playground to toy around with unconventional ideas without stretching it out over a longer period where it would lose its welcome. I think it worked, and this part will stand out whenever I remember World of Goo 2.

The soundtrack to the original was rather whimsical. Although the soundtrack to this is almost entirely the same songs as the original, it's done with different instruments, and has a very different sound texture. A few sound like they're performed by a mariachi band. I swear that one is from Little Inferno. I'll be listening to this for a while.

I didn't buy this on Steam. It's on the Epic store, because they signed a deal with them. I got it on their official site, which goes through Humble Bundle. They're asking $30, which I feel is about right if you liked the original.
