Thanks for the nice feedback. Would love to see some screenshots what you did in the play time :-). Animals would indeed be a nice addition. Agriculture is also a great suggestion (and probably a bit easier to add as a basic mechanic compared to animals). Multiplayer on the other hand would be a huge undertaking and will need to wait until I have implemented a lot more basic mechanics.
Regarding joystick movement: I plan at the moment to not add it as the core idea of this prototype is to explore how physical interaction and actual effort in achieving things will shape the game-play mechanics and features I can add.
