Ya elevator error. Nice work and easy puzzle. Thanks for creating.

Not bad for first time. You even have cubes in the tubes in the background. Most people don't add that on their first map. Others mention the elevator not working. Are you using arrival/departure_transition_ents.vmf?

This is really impressive for a first hammer map, I must say. Though the puzzle was very easy, it still was quite enjoyable. Good job!

Easy but good design. You need to make a full compile before publishing:

Elevator.exe has stopped responding. Should be fixed :)

Good Chamber

:D. If you have got broken elevator on the start, just reload testchamber it will fix it, if it not just type sv_cheats 1 and noclip in console.

Here is my blind playthrough https://youtu.be/xUgoZCEXmGc Easy puzzle but has good detail!

I did not trust the fling at the start, or the placement of the pneumatic vent. cool chamber though.
