Text on Keke is Rock lets Keke disappear

When I push "Rock" up a Rock will spawn Keke's tile. Now there should be a Keke and a Rock on that tile but Keke disappears.

In this example when I push "Ice" to the left an Ice and a Lava Block will be on the same tile without the Lava disappearing.

Why?

Ok, it happening two thing. The first one is that the text TEXT became a ROCK. But since the text TEXT disapear, it leave only KEKE IS ROCK (the ON without prefix can't form a valid phrase) so...you have two ROCK in the same tile.

For the lava not disappearing, that's only because there is a rule on top left that prevent transformation to lava : LAVA IS LAVA

Ahh thanks!
But when I push the two Rocks in the water both will sink. I always thought that when you have two tiles stacked it will only sink one at the time.

Yeah...I've wished that too, but no. In that scenario, everyone perish together.

When it comes to destruction-based properties only OPEN/SHUT will work that way (meaning that two SHUT objects on a single OPEN object will destroy only one of SHUT objects).

I'm curious, can you tell me in what level that rule can be tested?

Not sure about a level with two SHUT objects and one OPEN object, but a level with two OPEN objects and one SHUT object that comes to my mind is Metacognition. But I believe it works similar way - one OPEN object on two SHUT objects doestroys only one SHUT object and one SHUT object on two OPEN objects, makes only one OPEN object disappear.

The double-open making only one open disappear can also be seen on the level "Factory", fyi
