Most instructions are in the project. Press Space for an example, you may not use the example but like I said feel free to be inspired by it and create something with a similar idea. You do not have to stay in vector mode but I would advise it, they look a lot better in vector. Deadline for the first round is November 1st All entries submitted by then will be judged and the top 3 will move on to the next round. There will only be two rounds.
Thanks @ElsaOnline for hosting a great contest! I hope I win, because I worked on this for HOURS.
