Thanks for playing and providing feedback!
The controls button was intended but we ran out of time and thus disabled the button. Hope to add a controls or more like how to play menu sometime.
As for where to go, each level has an exit marked by red smoke. The level size makes it hard to find but our recent udpate makes this much more doable. There is a marker on your radar now once combat completes and you now see a big blue column of light coming from the exit to help guide you to it.
Hope these changes + a few extra make the game more fun to play.
