That's quite a bit if time! Thanks a lot for playing and your words honor me, I'm glad to hear you're enjoying your time with it^^
I actually haven't decided yet, mainly I wanted to see how much interest the demo gathers in the first place. Since the feedback has been very positive and also helpful I definitely plan on keep developing it into a full game with a lot more varitiy and new stuff.
So I unfortunately can't say that yet, currently my focus on in developing the game. Once that is done I will think about that. As for price, I also have no idea yet since I don't know how big the scope may get but in no case I would plan to sell it for very much.
Hope this gives at least a somewhat satisfying answer, and thanks a lot again for the kind words^^
If you ever should have any more questions, always feel free to ask.
