Alright, so Super Doki Doki World is complete! Thanks to everyone who played the demos and are continuing to offer feedback: it's very appreciated!

Final Version
...but there are still a bunch of little things that haven't been addressed due to Nagademo time constraints, such as graphical fixes, a few cheap shots, a couple of NPCs that should have respawn points so the player doesn't get trapped, etc. But it's mostly minor stuff! We'll take a look at that stuff this week. If you have any suggestions for tweaks to the levels, feel free to offer them: I know nin8halos already mentioned a few things that we'll need to look at. Y'all are basically our testers on this one! (Mainly because it took us up to the night of June 30th to pull it together, haha.)

Guesses?
So I was thinking: does anyone want to take a crack at who designed each level? Some of them were collaborations, but most aren't. That was one of the fun things about Mario vs. the Moon Base: as a tester, I tried to figure out who designed what level. I got a few right, but it was pretty tough.

SMB2 mechanics
I came to really appreciate the SMB2 throwing mechanics during the creation of this game. It adds so much more action to the levels, as long as there aren't any cheap tricks along the way. One of the tricky things was making sure that bombs were throwable by all characters, since Mario/Luigi and Peach/Toad have different "throwing motions". Another big challenge was implementing locks and keys, because they can mess up the pacing of a level and force the checkpoint to be either too early or too late in a level.

Red Coin segments
One thing I noticed is that our later levels didn't feature as many red coin bonuses as the early levels. This was partially intentional (at least in my levels) because I wanted the emphasis to be on the challenge at that point. In hindsight, another red coin segment or two might've worked in Worlds 5 and 6. Perhaps one such segment should be added to the flying shoe area of Climbing Climbing Beanstalks? And maybe another segment during the maze of Twisty Twisty Tomb? Hmm...
