At this point in time, I don't think I'll ever go back to that previous build – my most immediate goal in life right now is to try to get this game to the point that it's good enough to become my livelihood, and I have taken the game in this particular direction now because I think this latest version has a better shot of (eventually, as I've still got a lot of work to do) fulfilling that goal than the previous ones.
As for your actual question, no, unfortunately – I have since moved on from that previous build (the first person one) and am now dedicating all of my time to this latest iteration; game development by its very nature is a very long and tedious process, and if it were possible for me to sustain working on different builds or projects at the same time, I would do so, but I am constrained by time and the physical limitations of my body – so all my time and effort now must be dedicated to this latest build (on which all my hopes and dreams lie).
