Thx for the input. Yeah the car parking could use some stripes and such! I also felt it was quite empty, though I like it as the puzzle it is right now. Maybe I can add a few pillars as well.

Yeah I know the levels feel quite empty, but the problem is there aren't enough art items to keep enough variety. It is a huge art gallery after all, so it makes sense if a few parts are empty. I'll try adding some more things though, maybe using more different floors, so you have a more vibrant color scheme. If you go to the higher floors you'll also notice several rooms without lasers. But yeah, I do like lasers, they're one of the few ways to make things hard and create nice puzzles.

I haven't completed the level because it's too hard, but here's some criticism!

I think overall the level feels empty, maybe it lacks decorations and furniture, and the floors are too big? For example the parking is empty, there are only a few cars and lasers, there are no white lines on the ground and it's way too yellow... it doesn't look like a parking,

Now the positive:

Your modern art section is funny, the debris and giant octopus as "art", haha :)

You really nailed the lasers "tempo" too. Each room has its own very precise tempo, and if you're half a second too late you're caught. It's great, BUT I feel like you use it too much... but maybe that's the only way to make things extremely hard?
