The first one is “fight”, and everything is clear – you chose a monster and start a battle, and try to do everything to make your contestant’s health reach zero. You can choose “act”, and here there is a wide range of actions, depending on you are facing at the moment.

Sorry about the audio for some people, the current method relies on the system caching the sounds and for some it just constantly loads the files causing audio lag. I will recode soon.
