My character is Vitellary.

I haven't made Ved color entities yet, so the start point and missing crewmates still show up as white. (Vitellary's color looks a bit like white I guess?)

As for a test button, if I added a test function to Ved I'd need to implement VVVVVV's physics too, and that would need quite a large amount of work, and I'd probably never be able to make it 100% accurate (so a jump from one platform to another might be possible in Ved, then you release the level and it turns out it isn't possible at all in VVVVVV). Instead, I'll make it so you can click a place to test from, and then Ved will immediately create a save file with those coordinates, which you can then load in VVVVVV.

EDIT: Crewmates and the start point have the correct colors, I still need to implement a "Test in VVVVVV" feature.

EDIT (previous edit was 06.09.2015 d.m.y):
Alright, so I never implemented the savefile feature, because in practice, it's much faster and easier to just keep the level open in VVVVVV at the same time, pressing L+enter there, and moving to the correct room. The closest we've gotten to an actual playtesting feature inside Ved is my April Fools' joke (https://tolp.nl/forum/index.php?topic=3938.0) (also, see puzzle) and I'm not sure if there'll ever be a special version of M&P implemented. If VVVVVV were to become open-source later, I'd probably work on that. But for now, I'll change the status of this from "in process" to "completed".
