Honestly the mate here has a point, the mere fact that they have kept themselves from getting the money off the SS and other mediums is quite comendable, when others who do this kind of stuff just keep it up for as long as possible.
Yeah, they have spoken about release dates quite the many times, but honestly its understandable, for as far as we know, they are only one person, who has little to no experience, who just do this for the mere fact of making it. As someone who also creates (mostly writing and drawing) i also understand the appeal of saying a date just to try to ground oneself into it, even if in actually its not going to happen.
To the people who donated, yeah they can be mad (I donated too in its moment), but it was quite little money, and i enjoyed the game so far, so i say "it was worth my 5 bucks", if you paid more, eh, thats in discretion of each one of us to give as much as we think its worth giving, if you came out dissapointed, well, sometimes things end up like that, but at least you werent dragged along and used like other projects.
Because at the end of the day, the game IS free, and should be treated as such. A small project from someone who just wants to make something.
Honestly i wouldnt be surprised if the game isnt finished (small games with lone devs arent known to last very long unless they are really small in scope). So i dont set my expectations high, but if it happens, it would be a nice surprise.
