I really enjoyed the intensity of the combat scenes against the enemies

this is listed in portal

how to escape:

Step 1:

Press "V" on keyboard

Step 2:

Fly away

this is so old

good map for a first time map maker, though I would reccomend adding more decorations and improving the ending, you can easily see the end of the map

very nice!

Is good.

There are some rooms that seems to have no entry except of air vents, which doesn't make sense outside of gameplay.
Maybe add a lock door or two, even if it leads to nowhere.
But still, I like it.

please make more of these adventure maps

fixed

This is pretty good for a "first time" singleplayer map; hope you keep doing more of these!

Also, there are errors at the last part of the map; I think it's the trees.

epic

good job for a first map :D

Nice

Very well made. Congrats !
