I wanted to try to make a mini story where you need to get your beloved companion cube.

I need to change a lot of things and add sound effects, more lighting and animations also need to change some of the textures and decals. I tried to have some dirty aperture as well as clean aperture and I need to add game text.

It is not a hard map but hopefully people enjoy it anyway

Grats on your first map, but it's still too rough for what you want to achieve. Puzzles are really simple: how about having 3 of them in a single room, which trigger 3 locks for a door?

Also, was it intended that with the 2 turrets, 1 of them requires the sphere to be destroyed? That's one cool move.

I am aware of its faults I think I was trying to achieve too much and due to my lack of experience with hammer some parts where a bit rubbish. I think I will make smaller but harder maps for now and make this one better when I have more experience

I'm playing custom maps and record my first time of playing them. So the run is not perfect and may not use only intended ways, but maybe it can let you see how other people may understand the map or you could just enjoy someone playing this map for entertainment.
Anyways, here is the recording:
