Yes, I'm sorry about that. I know it's very confusing (and also i explained it in Spanish, so I understand the confusion.). Basically, you use the mouse and left button to move the wizard. After that, the enemies will move and your "potion turn" will start. You can grab your potion with the "P" key and hide it again with the same key, but it won't do anything because I couldn't put it on the game (I had no more time, sorry). To go to the next turn you can press "SPACE BAR" at any time (you will need to do it on the potion turn). Your goal is to reach the stairs. I hope you understand it more now, and thanks for playing ^^.
