1. Variety in propulsion methods. Too many launchpads can seriously lower your rating. Take a look at this for tips on the propulsion methods: http://metanet.2.forumer.com/index.php?showtopic=14692
2. Enemies/close calls. These are what makes a dda fun to watch, and therefore well-made.
Overall, though, it's not bad for the first.

It's clear to me from the definitive style of this map that you definitely have some skill as a mapmaker. This is significantly more interesting than my first DDA. However, as is always the case with first-timers, you have quite a bit to learn in terms of DDAs.

It seemed that halfway through making the level, you discovered how to use trap door propulsion, which is good. The fewer launchpads you can use, the better. You should watch some of the really good DDAs to learn how to use thwumps and bounce blocks.

Try to avoid repetition. The section in the upper left where the ninja keeps hitting the thwump over and over again was extremely boring.

One laser drone is not enough! Close calls are what make DDAs exciting. The more attacks, the better.

like jack_hammer4 said....not that good, but your first ;)

but it's so much better than my first (http://numa.notdot.net/map/86400) --> this one is really bad^^

but keep on making maps!! (:

It takes too long to get through some of the parts.
and, i agree with Dark_Saruman

Nice try, but it doesn't work.

its not that good.. but since its ure first DDA.. it alrite. 3/5

I hope it's the last one too...
