I haven't tried the demo, but I've definitely lost a lot of confidence in the project. I pledged $75. I will not be putting more towards it.
I get that it is difficult to budget this stuff. I was expecting something low tech and indie looking with some fun dialogue, and I think they want more, which has put them in a bad spot. I don't regret the bid, I think it is a fair price for a bit of reminiscence of my childhood favorites.
The Space Quest team seems to be stuck in a similar state.
