Thank you for feedback, I really appreciate it !
And for your points - Unfortunatelly, I haven't been able to replicate the problem with walking speed. What version of the game have you played? Win, mac or Web? I'm not able to test the mac version...
And you are right with the instructions. I added controls to the game description.
But if you thought of adding instructions of what to do directly to the game, I disagree. I would like player to explore the world and figure out what to do as well as what happened to the main character all by himself. In my opinion, this is the major part of this game concept.
