This is a good game, with no problems. Adding a speed up button would just ruin it. They keep at at that speed for a reason. Tactics. A mute button? Who needs one? If your listening to music just mute internet explorer, (or which ever browser you use) and if you're listening to it on youtube, open another browser for it... then mute the other one.
There are no problems with this game. It's fantastic.
Ok im going to be honest here. Who needs a guide to level up? I mean well done on finding out how many points you get for making games but thats about it. Yeah the music is from The legend of zelda(tm) Ocerina of time. The original and best.
