Glad you liked it! It took a ton of practice and planning ahead of time to get the time down to 3.
You totally should join it’s a lot of fun! It’s really more of an honor-code kinda system. Pretty much, I just looked at my starting time and when I took a break I’d figure out how much time I used up and add that to my total time. Once I started to get close to the 3 hour mark that’s when I built the game and submitted the project.
