i think you could have made some puzzle for geting the cube of the room with the aereal faith plates.
anyway, an simple but, in some way, funny map.

it was fun and easy...

Simple but fun, big faith plate chamber was a but bland but overall OK.

this map is nice but very easy. no challenge at all, not even is the "looking for the cubes" thing.

Any puzzle with fizzlers you need a cube dropper just in case of accidental fizzling. It is possible to carry the first cube to the fizzler-funnel room and lose it. Then you are trapped and can't get back to the three cube buttons. Using angled panels to block off an area that is intertwined with the rest of the puzzle is a very common mistake here on the workshop because most applications, most people don't anticipate possible trapping.

Try my map maybe?

By no means difficult but a bit of fun to complete. The faith plate room could do with some extra layers of complexity and you could add a third room to make the first box harder to get, you're way off the item limit so it's achieveable.

I've got a little collection of chambers going and I'm always interested in feedback. I'd be grateful if you'd have a look:
