Hi Simsim133!
That question warrants a bit of an explanation, but yes, we have plans to extend the game. With that said, I am not sure when (if ever) we will find the time to start working on it. But Solitude is quite dear to us. It is the first game my wife and I worked on together, and we would love to take the idea further.
This was a game jam game, and we are aware that the controls and gameplay are a long way away from being ready. We have learned a lot in the mean time and will be completely redoing the game once we get around to it!
