You do manage to get a few close calls with the thwumps and rockets, but it's just not that much fun to watch. And it's really laggy on my old computer, so I have to underclock it to prevent that (though that's not your fault). But basically it just needs to be more interesting. The jumppads are pulling the ninja away from the dangerous things and the point of a DDA is to keep the ninja constantly as close to the dangerous things as possible. 2/5

As for the whole jumppad controversy, I'm on the side of "If it generates close calls and is generally entertaining, then I don't care what you use. And vice versa." PsychoSnail made a mostly jumppad DDA and everyone gave him hell about it, but I loved it.

except for the fact that they're easy to use. Since they're so easy to use, though, my standards for them are higher than with other forms of propulsion, since you should be able to get better close calls with them. For some reason, people seem to have something against launchpads, thinking that it's some sort of sin to use a launchpad, but there really isn't much of a reason to think of launchpads that way. They're propulsion just as much as thwumps, doors, and bounceblocks are.
The purpose of a DDA is to entertain and to excite. As long as a DDA can do that, it is good.

there are good launchpad ddas. they're good as long as there are many close calls, which there aren't
some of the thwumps were unnecessary.

never make a DDA that is entire launchpad-powered. NEVER.

Ever.

but after that too many launchpads were leading away from the rockets and the action. Don't put launchpads that direct the ninja away from the action. Launchpads are the easiest to use of all the propulsion methods - that means you should be able to get a close call with almost every launchpad you place. It was also quite short, so you should use more of the space.
