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.

I hear many game maker devs talking about gm48 so I decided to try it out myself and it was really fun it pushed me to my limits and made me create new techniques

Some of the most fun and engaging game developing experiences I've ever had have been during my participation in GM(48).

I encourage all GameMaker enthusiasts to give it a go.

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.

As draining and as tiring hacking away at a game for 48 hours is, I'm super glad I participated in my first GM48. It was a very rewarding and exciting experience and I hope I will have the chance to do many more of these in the future!

Participating in GM48 was great! I've never felt this motivated to make something ever before. I'm definitely going to try and participate in future GM48s.

I agree wholeheartedly with MintyPython's testimonial: "GM48 is an inspiring and inclusive event fit for beginners and veterans alike. There's no better place for GameMaker devs to really come together as a community and show off what they've got."

Loved the jam. Teaming up and making something great in 48 hours (with some sleep) was a great experience. If you make stuff in Game Maker, this is the jam for you.

No other game jam offers an opportunity to test your skills and learn with a variety of unique themes as much as the GM(48) does. I'd highly recommend it to everyone, from beginners to professionals.

It's always a challenge to create something in such a short time but one of the most useful aspects of the game jam is the feedback. Often the feedback will highlight something positive or areas of improvement which gives you direction and snaps you out of the bubble you are in.

It's the only GameMaker game jam that's worth participating in.

It's well-supported and every time I'm shocked at how good the game entries are!

It pushes me to be a faster, better developer.
