Hey Shmoopers, thank you for the kind words I'm glad you enjoy it :) the 'rainbow/party' command flashed colors and I decided to remove it because of photo sensitivity. I tried making a fire that was rainbow colored and didn't flash through the colors, but it was muddy and didn't look like a rainbow or very good. If I can make it look decent I'll get it in the next update :) The 'touch' command is one that I decided not to re-implement. Pixel Fireplace is meant to be a nice soothing experience. That command brings to mind pain, and I always felt it didn't really belong so it didn't make the cut for the rewrite. The number 0 is a bug, I have no idea why it's doing that heh. Thank you for letting me know!
I'll add a note to the 1.2.2 DevLog about 'rainbow' 'touch' and the bug with 0.
