So this is just a tech demo. My priority right now is to get it running at at least 30fps.
Once that's done, there will be tweaks to the demo gameplay (fixing controls, some kind of auto-aim, fix the occasional freezes) then it will be into the full game.
That will be very different. It'll have missions, pick ups, buildings and various level themes (e.g jungle, urban etc.)
But it's going to take time, I only have small amounts of gamedev time unfortunately
