I tested the level out and overall I like it a lot.
This can be a good starting blueprint for creating a level that you know is going to utilize timers with do-loops
I know the level's in beta and that you're going to be updating it, I just want to let you know some bugs that you may or may not know about. The tsetup10 script uses the wrong flags, so trying to use this script to set the timer won't work. It would be nice if there was some ground to stand on for the other rooms, and also placing down some scripts for an example so people can see it in Ved would be nice! Additionally, people who are disabling screen effects (like me) actually won't be able to see the flash so including a playef(9) would be great!
If you're okay with it, I'd love to help you out on this. I think VVVVVV is lacking a lot of resources for people who wish to learn more about internal scripting and I think creating a level focused around that would be a huge help to newcomers wishing to create a level that utilizes more complicated scripting.
