and get up to the key, over the trapdoor and then i get stuck coming down with the thwumps...

also, the laser drone in the wall is cool, but i can avoid the switch and still get all the gold :)

Don't use the "fun--------------------annoy" thing on maps. But I love the other, A Hard Days Work. (=)!!

at first.
A lots of well thinked traps and all that kind of stuff.
Your level is well done, nice tileset, nice idea (the drones coming out of the walls were real cool), but I think you fail about giving "fun" to the player (and when you see the thousands of map existing on numa)...
When I try your level, and start all over again because of traps, I'm first like "hahaha ... wow! what a trap !" and 153 tries after, I'm like "ok, no more, I'll try some other map !".
I have a map like that too (less traps, but still there are some) : http://numa.notdot.net/map/38090 ... you can read CheeseGod's comment...
Try my map, you'll see... funny at first, annoying at the end... I have a complete demo, so long it bugged the site, so I couldn't copy/paste as usual !
I think this kind of "long walk map" needs a demo from the creator, just to make a show, and not a real action-map...
I liked your map, and ideas (use them again), though, so I'll give a 4/5.
You're talented, so think more of action-fun for the player, and you'll make great maps. Ciao.

Hidden traps are just... annoying. Nice n-art of the symbol, though.
