Played through everything 1.12 has to offer and there are a lot of goods in here, although there are some bads too.
Starting from good; centipede is scary as fuck on all stages of gameplay. At first, its moving animation and model are incredible. But as any other scary monster, you get used to the design. What I couldn't get over is sounds that centipede makes. They aren't particulary scary, just really uncomfortable to hear, which is great. First time I heard them, it motivated me to not get anywhere close to it. Good job. Secondly, tower designs are fine. There are multiple paths you can take, which is incredibly good for the gameplay and allows to not get stuck on the same place for too long. Thirdly, textures, effects and other animations are good, style is solid.
Now the bad; In the first kiln mode centipede that crawls out of the hole near the start of the level always spawn on the same side of the wall. Would be perfect if it had spawn ring instead of spawn point.
For me thats it.
