...You need to put in enemies and it's pretty boring running all over the map unlocking doors...The gold is ugly, too.

Uh... no. I don't think you should be giving advice about levels. First of all, way too many trapdoors. Most people don't find it fun to run down a flat stretch of tile, pick up a switch, and run all the way back just to do the same thing again and again. Also, way too much gold. You really don't need that much gold. I don't care how cool it looks. No. Also, don't hide enemies under anything. You can see the enemies being put in while the level is loading, so it's not like there is any surprise to it. The huge pit of floor puppies is completely pointless as well, because the ninja doesn't even have to travel down there to complete the level. One would just do the same job, anyway. Don't listen to mike. you don't need more enemies, and NO TRAP DOORS TO TRAP YOU IN A ROOM! NO! NO! NO! NO! NO! NO! NO! NO! NO!

For next time, just remember. Simplicity is always better.

Well, I guess Ill be the first.

Perhaps add some trap doors so that going the wrong way will trap you. Of course, there's always more enemies.
