Nice map, I think you did a GREAT job for a first map. Not sure if you intended something though. In the upper right corner of the map you have a trap door paced over a normal door. There are some bugs that can creep in when you do that. In this case, the normal door made the trap door useless so you just fall right through it. I think if you reversed the order you placed them it would work fine. This is where good play testing comes in. If you intended it, then ignore these comments. :D
