The price will be gradually risen as new content and features are implemented. The raise will be reasonable, reflecting the number of hours that has been put into adding new content and occur as the game transitions from alpha to beta and then from beta to full.
Nice work guys, congratulations. The development has been nice to seen. I hope this will continue and it will become one of the best games ever made! I can’t wait to get it out of my wishlist again and play it.
Most likely starting? I think 20 is reasonable for early access given how polished the game already looks and how much depth it seat has? But anything now is idle speculation really.
