I'm quite a fast reader, even in English which is my second language and I know Lock for being rather humble. It's not just "a bit over an hour", it is more in my opinion. I've played AVNs that had 2 or 3 chapters for the lenght of this ch1.
The quality of writing (as spelling, grammar etc.) is top notch and the images, scenes and renders are also up to the tiny details.
Lockheart puts a ton of passion in his work and earns some donation for that.
The idea selling each chapter pre public release is rather great and customer friendy. You can wait about tow weeks or pay a small fee if you don't want to support monthly like on patreon or subscribestar - taking the risk that chapter take ages while you pay... which won't happen with Lockheart but I know everyone hast mad his oder her bad experience with that.
