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 platform is great for seeing what is possible in 48 hours. Making Color Pickers help point out some issues I run into when making games.

This was a tough one. It was a challenging theme. I love seeing what other people come up with with theme-based Jams. So cool how other people think.

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!

I've had a lot of fun making a game for this jam. Making a game in 48 hours isn't as hard as it sounds but it's definitely really tiring. Well, at least I'm kind of satisfied with my result!

GM48 was difficult but rewarding. Two days don't seem as much time but many things can be made in this timespan.

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.

First GM48 was very over ambitious and it turned out to be a hot mess. Met some very nice people and will hopefully work with them in the future

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