heh, don't worry about keyboard input, I am depending on it too, because on my work table is no space for mouse, only in case I am lefthander, what I really am not.
So there will be choice to choose between keyboard and mouse, I hope I will find a time to transfer second laptop under main desk of my table, so I can play bc with mouse too. Now, there are much harder decisions like should animals move often to better recognition of them also for cost, that it looks really stupid?
Anyway I have all done about animals from start of September, so now there are remaining just three things to make. Active mobs like zombies, skeletons, etc. rivers, what I haven't idea how to do them yet and NAT, my developed technyque to make better orientation in 3D space for blinds. Last thing I have already in building phase. I was able to see tree with it to distance about 20 blocks, and not only one, but layer of trees around me, hovever I did remake and now it doesn't work, so I am on the beginning lol.
After these will be done, first beta can be released. There isn't multiplayer and plan to do it yet, hovever I hope it will take few hours to do it, so I am focusing primary on game system, before release I will decide if include it in beta or not.
