I'm glad you found the feedback useful!
I would definitely pay for Early Access. 100%. If it means you being able to get the art assets that you need, then Early Access could only be a good thing. What you have done so far is already polished enough for such an endeavour, and I haven't come across any bugs so far, so if you get it to a state you're happy with and go in that direction, I'm totally on board.
I love how HDS is a big love-letter to the experiences I grew up with. To see this expanded and built on is definitely worth paying for :)
