$10 gets you access to all my stories, betas, betas for other games, and basically everything else I post including books. It's a bit reductionist to just see it as paying for each version of The Hotel, but I guess if that's all you care about I could see it being a bad deal.
Buying the game on itch.io gets you access to all future versions for free. Pledging is basically just getting access to the betas and early access to the full updates if all you care about is The Hotel.
