There were other comments on your post last time indicating that people felt your attitude to community management was exclusive and shitty, and I would really hate for some bright eyed indie game dev out there who doesn't have a steam page yet or whatever random criterion you use to "weed out" people and don't share up front to feel excluded like I did.
Were you able to finish the game you were working on?
I learnt how to do simple 2d physics from scratch, collision subsystems, a UI subsystem, setting up tilemaps, implementing nav meshes and fluid sim, shadows and lights, and support for tons of sprites, experimenting with impostors for more realistic assets, and am now in the process of spinning up prototypes from the base code that I have so far.
I don't think I will have a finished game any time soon(the next year or so), since I'm still iterating on the core game mechanics.
