Not for begginers that mess around, my but.

we all know that everybody has done this, though nobody has submitted it on NUMA, because it would get reviews similar to yours.

is.
Survival.

Survival is supposed to have... something.
Some sort of structure to interact with.
Not a trap-door.

I think those lots of rockets looked cool.
Now honestly, six months is excessive, look at good authors and take heed of their works.
I have no maps submitted on NUMA, but I consider that to be better than having filled the recent maps listing with several shitty maps which I made in like 2 minutes and are just crap anyway.

Nononononono. That's too long and you'll likely get bored if you have no one to share them with. Otherwise I agree with both of these dudes, except for XYPTERO's author list: PALEMOON, sure, but I would think better authors to look at would be l_d [nmaps.net], atob [nmaps.net], etc.

but i have to agree with Avatar. Putting in lots of enemies takes no skill, and its the skill of creating a map that people like to see. Take a look around at other users. Play some of the maps by eganic, blue_tetris, PALEMOON, or Lucidium. Take ideas, and expand on them. Spend six months or so creating maps before you start submitting them on NUMA. Otherwise, you're going to get a lot of bad reviews coming from everybody else.

your maps suck. don't treat NUMA as just a place to post spam maps that take you two seconds just to put a bunch of crap on a map. take time with your maps. develop TILESETS and then work with a MINIMAL amount of enemies around the tiles to create a fun challenge. if you continue your maps like this, you're gonna end up hated by a lot of people. check out some other maps to get ideas if you want to.
