Why does my level have water physics?

[Chip Potato]

For some reason, the level I was creating suddenly has water physics, and I could swim on air. If you want to know just how ridiculous it is, the level I was working on was a lava cave. A lava cave! Why is this happening, and what can I do to stop it?

You might've pressed the Underwater Button in the Level Settings tab. If it says ON then click on it again so it says OFF

Did you select "water level" in the level settings by accident?

That... was actually the problem. Wow, how did I not notice that?

Anyways, thanks!
