Yeah, this seems fun and is interesting. Length of the demo is good IMO. Tells enough. I reckon this'll turn out great.

My one request may or may not be necessary, depending on what systems of interaction are available in the final game. The request is, when you do add invert Y to options please don't make the mistake some developers do which is for that option to apply inverted Y to everything. Generally inverted Y is good for look controls, but then sometimes the developer just makes that option apply everywhere, inverting in game cursors or other controls that aren't intuitive when inverted. But if the entire game controls with "manual manipulations" like in this demo then this shouldn't be an issue.

Otherwise, looking real tops.
