Hi ! Thanks for playing :D
It's indeed a gamejam game, but this game do have a special place in my heart, it's been a while, but I think still have the data somewhere.
I probably won't update the game in the near futur, but maybe if I feel like it at some point, your suggestions sound reasonable.
But I'm currently busy with my citybuilder "Storm Settlers" that is meant to be a game on steam.
