Too short. The author has some interesting story techniques.
However, in its present form it isn't worth a replay and I wouldn't use it as a map for guests.

Nevertheless, I believe you are the right kind of modder to author a compelling story. For instance, as a suggestion, the player has found resin beneath his garage and he is mining it. Every once in awhile as the story progresses, the player re-enters the world above through a sewer grate which is next to gun-upgrade station.

As the player moves through his tunnel, it ends where he broke into the antlion nest; and so these tunnels are larger and have some sections which are very large and full of eggs or food or larvae.

At another point, a combine soldier drops a couple of corpses into a sewer as you approach the grate. Then another cut-scene shows the ant-lions placing the corpses next to some head-crabs. Then they drop some resin.

Good escape map, but I got REALLY stuck at one point, didn't know where the hell to stick the crank. Spent easily 20 minutes JUST looking for the hidden ****** behind the *****. Still, I pressed on. It's well made, densely packed, good attention to detail.

Fun little escape room map, the puzzles were pretty good! I gotta say though, it took me a bit longer than 30 minutes hehe. That's a good thing though, I enjoyed it.

Good stuff! Love these kinda things

@cjp232008 Thanks for sharing your play through! When testing the map, that zombie made me jump almost every time even though I knew he was there!

i tried this for myself and i am ashamed https://www.youtube.com/watch?v=Lq1FYkW8qrU

This was pretty fun to play!

I love puzzles thanks for your great work!

Thanks now I feel stupid

I really really enjoyed this! I guess I'm not too good at this kind of thing cause I had to look at the video twice, but I still really liked the puzzles.

@Skummeh Thanks for sharing your play through! It was insightful seeing how you approached the puzzles and your thought process.

Nice job! I really liked the overall layout and structure as an escape room; it didn't have a lot of random clicking and searching to solve it. A bit more sound design would have helped it feel less empty, for example a bit of music with the first combat encounter. https://youtu.be/5RvIpviQSSE
