Shout out to Noita for having the same mechanic. In the default mode, you start with a flask of water, and if you get to the bottom of the first biome and go to the right, there's a lake of lava. A full flask is just enough to make a bridge of lava.

Worse, IRL molten lava is mostly solid like you see in the photo, not red water. If it's as viscous as water (or close to that), it's MUCH hotter and the air nearby would kill you. But that's how it's portrayed in the game. In a lot of games. Like Mario 1.

Getting back to Noita, to be fair to it, it is a pixel physics simulator. Every pixel's physics are simulated in real time. So it's not a pure bridge. Some pixels stay lava, and if you touch them, you take a slight amount of damage. Mostly if you're conservative with your water. Me, I like burrowing through the ceiling and dumping the lake above on it. Then again, if you can get under the lava, there's a nice little present waiting for you... best to get to the third biome and come up from under, though.
