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.

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!

I had a great time on this game jam. I found out about it the morning it started by a post on /r/gamemaker, so I'd like to thank the organisers for putting the word out there.

Although making two games instead of one wasn't ideal, it was a lot of fun to see how quickly I could create two small prototypes and made for a great challenge.

It's nice to hang out with other game makers while you're all frantically coding and making content as fast as you can!

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!

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.
