Hi! Thanks for playing our game! Towards the end of the game jam we haven't play tested it yet so when I played it, I realised it was really hard to find crystals. I implemented a thing where the crystals emitted a light every 10 seconds. After I did that though, I couldn't think of another idea to make it easier to find crystals but not too easy, so we just submitted it. I was also going to add a feature that allows you to mute the sounds or music or both, but I couldn't figure out how to do it, so I scrapped it.
