Thanks —!
Ha, I've never thought of it being like Moon Patrol before. Maybe when I start writing the music I should write a track that sounds like the music in Moon Patrol. That soundtrack still gets in my head after all these years.
As for more levels, I'm going to try to have the game all in one layout. So the game won't feature levels per se, but there will be unique areas to a larger unified game world. For now it'll be a small playable area until I get all the mechanics in. That way I can design the map based on the features I implement, instead of having to redesign an area because I cut a feature that wasn't working.
360° aiming was something I had thought about implementing but ultimately decided against it. I had a really good reason for not going that route, I just can't think of it at the moment.
