So I am still split on the game perspective. If I go isometric gameplay will be very maze based exploration. If I got side scroller, more linear platform based. Right now I'm leaning towards isometric.
Anyway I have been working on and off of this project for about a year now, it's lay dormant for the better part of the past 8 months or so. This is where I was at when I stopped working on it.
Using various assets from old projects, as well as some new I mocked up what I imagined a level to look like.
Using these parts:
I made this
The top of the tower
I'm still torn on perspectives, but my biggest fear is that I don't think I have the level design chops to make compelling gameplay for a side scroller.
