What a load of balls!

I cannot stress enough the importance of actually using droppers instead of just placing the cubes all over the place and hoping the player doesn't accidentally lose one. I had to use noclip at one point because the ball past the fizzler that can be turned off got stuck in the flip panel that was supposed to let me access it. Still, it wasn't horrible, just a little bit tedious. 3/10

I agree with Stagger Lee, there's too much walking (as said in the comment below). So my only and very general suggestion (it may be hard to do it) would be to decrease the distances one has to walk and make the part with laser cubes need less than 5 of them.
In the end was I supposed to place 4 balls like this screenshot ?

Two other maps of you I've played (Revenge and Flooded) were much better and I wanted to comment them, but it seems you have deleted or hidden them.
I also couldn't find the discussion thread in which I gave the link to my collection, do you still have it?

no i still have the links saved in comment histor thankfully.

Do you need the links to the other videos again?

toncica, no i didn't delete it, i was appreciating the feedback, not sure why it has gone, may have to repost!! Thanks for you review, its grtefully recieved.

Did you delete your topic in the discussion section? Looks like it's gone. I'm sorry if the criticism was too harsh. Sometimes I got feedback too which wasn't exactly flattering but in the long run I appreciated those honest opinions. It's always food for thought even if you disagree, while "nice map/was fun" does not do anything in my opinion.

Let's finish this. Like Stagger Lee I think there are too many cubes and spheres to be carried around but it kept me interested. I don't think it was trying to be too clever. On the contrary, during my playthrough I often thought about alternative designs which would make the puzzle work with less cubes. There are ways to make it more advanced in my view, maybe that would be "trying to be too clever" then though. Anyway, I saw potential in this map and I enjoyed my playtime. Difficulty 5/10

I see what you were after in this one but it suffers from almost trying to be too clever for clever's sake. There is way to much walking back and forth to each chamber to get a cube or a sphere and back again or to a different chanber, rinse, repeat for each button pushed or cube placed.

It's difficult but not in the avenue of problem solving. Just difficult in getting it done with the endless treks back and forth.
