The itch.io version doesn’t allow easy restarting of the level, you have to go into the fire in order to restart a level. There is a version on Discord if you want it, that does allow resetting the level.
For the instructions, just have the text already loaded on screen. It took forever for it to show all the words. You also need a level reset in case you get stuck. Sweet game though. A ton of fun. Reminds me of Solomon’s Key / Fire n’ Ice for NES.
