Thanks for the review! I am glad that the concept of the game was conveyed properly :).
Yes, zooming out and the ability to lock the camera is possible. I am also thinking about the possibility of controlling camera movements with WASD or directional arrows.
And in regards to speed, changes we might implement could be better AI and difficulty scaling up over time as the princess levels up, moving faster and faster. Hopefully this addresses this particular concern :P.
Will post a small update for the game following the GMTK voting end!
