Here are some things I’ve noticed when playing/rating some games:

• Vertical resolution is greater than 768, but there is no full screen option. This doesn’t work for people who have 1366×768 laptop screens
• The archive or exe name is just “submission”, “release”, “windows”, “ld31”, etc. Be sure to put your username, game name, or both in your file names. It makes it easy to remember who the game was made by, but also ensures that the folder of games being rated does not have overwrite issues, stomping other games.
• Lack of instructions or readme files. It’s really hard to play a game if it’s complicated and/or you don’t know what to do

Keep these in mind when submitting your game. I hope this was a helpful reminder
