Pixel Fireplace Lite is a cozy, type-controlled app. You can type commands to interact with the fire or just sit back and enjoy the warm glow of burning pixels.
Try roasting a 'MARSHMALLOW' or throwing in a 'FIRECRACKER'. You can add up to 5 logs at a time and each will burn for about a minute before turning into coals and going out.
The paid version Pixel Fireplace has much more durable logs and will get free special updates during the wintery months. Enjoy :D
Commands to try: LOG, MATCH, MARSHMALLOW, EAT, PHOTO, HELP, WATER.
