Very good first chamber. However, I didn't see the point in those turrets on the way down to the button because you can just drop the box down there...

Congratulations on your first published map. I hope you keep polishing your skills. A common flaw in many first (and second and third!) maps is that abundant portal surfaces can help the player bypass some puzzle elements. Here, for example, I had the sphere in its catcher before I left the entrance, and had the exit door open without disturbing a turret. I confess I used the blue gel to bounce out, but I suspect I could have got by without it.

its a great chamber!!!!! keep it up

Ball needs a dropper because you have goo present. The pit to the button is very unnecessary. Tedious activation. Possible to bypass needing blue gel.
