Is a concept I've sat with for almost 6 months now. I'm a huge fan of the mobile scene its drew me away from consoles and seeing the most popular gimmick which is endless running. Now I wanna build on that concept so I added a maze where players would have to navigate and collect 1000 coins without fail. All the coins are single file so its not hunting. On top of that you will have a monster chasing you.
To all my fellow designers this is for a mobile game so don't dwell on its simplicity.
