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 had a great time participating in gm(48) number 30. I was lucky and everything just seemed to gel. This is my first successful game jam with Game Maker so I was happy it went well!

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.

I had a perfect version at 7:00. Deadline gets extended 15 mins so I try to add one little thing to it. Fatal error on my submitted project with no way to fix one simple mistake that completely ruins an entire 48-hour slugfest BY MYSELF.

Probably won't be attending another.

This was my first game jam entry.

I wasnt able to wrap up a lot of the mechanics i was hoping for so by the end of the time and the game it was really a mess.

However I learned a lot from this game jam and am looking forward to making further entries, it was a blast.
