I usually join Ludum Dare and other local jams, but I believe that GM48 are the ones I enjoy most.

It's a way to see what someone can do in just 48 hours with Game Maker, and the source code is usually available to mess with and to learn about.

Even if you haven't been here from the start, this jam is really open and welcoming, for both beginners and experienced developers. It's a fantastic event to just sit down, make a game and have fun!

This project was a lot of fun. I streamed a good majority of my development and had a lot of fun doing so. The drive and push it gives you to make a full, complete project is very valuable.

GM48 rocks! I have learned so much during the 3 times my team has participated. The themes put us out of our comfort zone, and we learned so much in such a short time. Can't wait to go again!

GM48 is my absolute favorite jam to participate in. Everyone is very friendly and it's a great way to meet other Gamemaker developers while getting great practical experience with the software. I highly recommend that you join the Discord server to really complete the experience!

I'm sweating. I learned a lot in such a short amount of time (especially about time management). The 29th GM48 was my first jam and I'm happy with what I produced.

We all start somewhere and I'm so grateful for this opportunity.
