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.

It was fun to make a game about a kid shooting down an internet company under 48 hours

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.

This is the best gamedev-related event I have ever had the honor to participate in. I had a blast working on my games and it's an experience no one should miss!

The Jam was a lot of fun! One tip I can give to future participants: Nail down what you want to do as quickly as possible! If you don't, it might come around later and bring unwanted trouble!

GM(48) never fails to inspire and motivate me to make a game.

The community is awesome and I would've never made so many games without it.

It's the perfect balance between playing and making!

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'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!
