You can enter easily by just remixing, importing your design, and sharing the project here on Scratch. There is only one round, so you don't have to follow the contest at all - if you win, I will contact you. Once the contest is closed, I will share results the same day. So, don't be late, otherwise you might not get in!
200th follower @ailiz Quicktor is a quick vector design competition. Competitors have 10 days or less (depending on when you join) to complete their work. Contest is closed December 5th. Remixes posted on 5th and later will not be judged. I'm the only judge, and this is all my own opinion, so don't get disheartened if you don't win!
