Next steps for students’ project

I teach a basic course on game development, in which students design a game idea and write a digital prototype in Unity – about 5 minutes demonstrating the main idea and gameplay. Some of the teams did really great jobs and I would like to encourage them to continue developing their game beyond the course, but I am not sure what the next steps should be. In particular:

  • Where can they get more professional review on their prototype? There are websites that review games, but usually they are looking for complete games, not just prototypes.
  • Where can they get playtesters that will help them improve their prototype and make it a full game? Currently their game is in, but it is hard to draw attention to it.
