Two regrets:
First off, I didn't even find out about this jam until the first 24 or so hours had already passed by. If I had known about it and started earlier, I could have accomplished way more.
Second, I added a timer to my game which vaults you back to the title screen. Then, for some of the levels, I gave hardly any time at all to solve them. Since mine is a top-down puzzler based upon navigating using only sound, this made some parts punishingly difficult. I'm afraid I made it too challenging and frustrating, meaning nobody will play until the end :(
I did, however, add the solutions to all the puzzles onto the game page. That way, if players want hints, they can refer back to it.
My game is called Echolocation. Check it out!
