also can my game be small but focus more on quality ??
When submissions close everyone will be given time to rate other entries. If you want to increase your chances of having your game rated I'd recommend playing other entries and leaving feedback. Ratings are weighted so that the number of ratings is taken into account. I wouldn't worry about it too much. Just make the best game you can within the timeframe and have fun! The duration of the game also doesn't matter too much as long as it's a good experience.
