What is the gm(48)?
The gm(48) is a quarterly community event centered around a competition, in which game developers, by themselves solo or in teams, must develop a game in GameMaker Studio 2 in 48 hours.
These competitions are commonly referred to as game jams. Once the games have been submitted, everyone will play, rate and critique the submissions for two weeks, the ratings from which the top three games will receive licenses to GameMaker Studio 2 as prizes.
The game jam is open to GameMaker Studio 2 developers of all ages, abilities and backgrounds. Beginner or expert, young or old, artist or programmer, all are welcome in the gm(48) game jam community.
You participate by creating a game from scratch in the 48 hours from when the game jam starts to when it ends.
Before the deadline is reached, you must submit your game to the website. You'll need an account on the website in order to do that.
You don't have to register or sign up before the game jam starts.
Check out our Quick Guide for more information.
The score is calculated using the Bayesian average method. This means that a game with one 100% rating can't score higher than a game with five 80% ratings. In other words, the number of ratings a game has received plays a role in calculating the score. That's why the averages in the rating categories doesn't match up with the final score.

It was a gloomy theme for me, and looking back it was fun to make, especially the voice stuff! :D
First time in Gm48. Really tough for me and my team because we had been too ambitious and the low experience didn't help! Anyway, very funny, I will participate again.
I've done this a couple times now, and each time is more fun than the last. It's cool seeing how I've improved since I started, and overall participating has been a great deal of fun!
This jam was a fun experience, and I look forward to the next GM48!
This was a tough one. It was a challenging theme. I love seeing what other people come up with with theme-based Jams. So cool how other people think.
This is a great game jam. I joined this game jam when i was only 2 weeks into coding, and i enjoyed every second.
In my project Countdown is a project in which I have not put all my work, but in The Legend of Princess Kidnap yes. I hope you like it
GM48 is not just a jam it is a fun way to test our knowledge.It makes us think in different ways to come up with good ideas.I think everyone should try it.While I was creating Static I learned a lot about pixel art and my weaknesses in game development.I really enjoyed it.
I always have fun in this game jam. Every time I participate I have an amazing time and always push myself to learn something new. The feedback is always super useful, and to any new comers to game development I recommend this game jam!
Phew! What a ride gm(48) is! I certaintly learned a ton from the jam, and it's inspired a game idea for me!
If you want be a better game developer in general, and spark some game ideas in your head, gm(48) is the place for you!
GM48's game jams are pretty challenging, as there are a lot of awesome and talented artists, designers and coders who participate in them.

What would you develop?
It's never too late to get started with GameMaker Studio 2. Your next game could be one of these, so why not book a weekend for the game jam and see what you would create from scratch.
Use the game jam as a way to spark an idea from nothing to a playable prototype. Many developers use game jams to let loose their creativity and design crazy fun games.

Why Game Jams
Game jams are community events about making games set around a given theme within a time limit. By way of these constraints, your creativity and skill will be laser-focused on creating a game from nothing to something playable, and you gaining a ton of experience with your tools and constructive critcism from your fellow developers.
Don't get discouraged! Game jams can seem intimidating, and if they do, that's a good thing. That intimation will force you to work harder at becoming better. Watch this video by Shaun Spalding for tips on how to survive your first game jam. By the way, Shaun's game PokeyPoke was originally submitted to the 25th gm(48).
