Are you writing parser or choice based games? Because if you’re a parser person, ParserComp is this summer, and it’s a really friendly experience.
Here’s the sequence that worked for me when I was fresh off the boat:
1.) Write a game. Do NOT post it publicly anywhere.
2.) Ask for beta testers here, and do it pretty early, because there will be so much wrong with it that you will need a lot of time to fix it all. This is not a personal prediction about the quality of your games-- it’s just that a new author cannot predict all the ways in which players will do things differently than you expect. The expectations for implementation in the comps are high, and testers will help you get there. Also, for some reason no one can ever see all the typos and grammar problems in their own writing.
You will send the game to your testers via email or DM so that they can play it, but it isn’t published openly, which would disqualify you from almost every comp.
I cannot stress this enough: be open to criticism from your testers. Take a deep breath, shelve your ego, and give them rein to comment on the story, the writing, the ending(s), the puzzle quality-- everything. They will make your game better if you can take the gentle, polite, but firm criticism you will get if you allow it.
3.) Fix all the stuff your testers find, and then get a second round of testers and do all of #2 again.
4.) Submit your game and bite your fingernails until the reviews come in.
Edit:
Oh, and then your game will be out there and on IFDB for all to play. You can’t submit it to any other comps, but it will be eligible for any awards for that year.
