Answer 1

You should not make the background a color that literally hides the prisms in the wall. Couldn't see any of them the first time, missed the top one the second time and the bottom one I didn't find until now. Not cool.

Answer 2

So sorry. It didn't occur to me that they might have camouflaged.

Will remember to make a contrast between the prism and background in the future.

Answer 3

Try to make a cutout in the wall with spikes on the inside so that they don't spread dust either, that way it's even more obvious that there is an enemy there that needs to be cleared.

Answer 4

Noted :)
