How slow? Hmm? You're not telling me how much mHz or gHz you have. And what ms/f? Higher than 120 is unacceptable.

you must have a pds computer if it lags on yours, mine's slow and it doesnt lag.

I'm not rating it down directly cause of lag.
It's because he could've avoided it altogether by using less enemies.
That make it clearer?

kinda laggy for me meh

But not much variation. Try to use a few different objects next time. 3.5/5

Whether it lags on retro computers isn't really relevant, although you might want to include a warning in the description. Rating a map poorly because your computer is slow is like saying a book is terrible because it's written in Japanese and you can't read it.

Fine. One last constructive comment.

USE TRAP DOOR PROPULSION DAM IT

I forgot to mention to try to use as many different kinds of objects unless they're enemies that add a lot of lag (for those only add one)

Alright...

First, it lags like S*** on my 800mHz computer. Be considerate for us ppl with retro comps!
Second, don't do "the many launch pads, overused gold delay, and the fact that the ninja dies at the end".
I think you should cut down on the laser drones too.
For a first DDA, its a 3/5. Sorry.
And I don't get why these other people are rating it so high.

Loved the close calls. 4/5

That was kick-ass. 4/5
