Fantastic! Strong theming, a nice transition from 'narrative RPG' to 'Prestige loop maximizing' play, well paced while being surprisingly long. I like how you can earn an ending from the word go, and the prestige loops are for earning a better ending. I dig how the RPG exploration becomes a puzzle of maximization on consecutive playthroughs - it felt a little like the old 'Lock and Key' interactive fiction game in that regard.
Scratches the incremental game itch beautifully. Numbers get larger, and progression gets faster, while having enough long and short term decisions for the player to keep it engaging. It never goes from Game to Spreadsheet territory, like most incrementals do.
Nearly perfect. I feel like the purchases that can be toggled on and off before a run could be marked as such before purchase, so the player knows they are not committing to always doing X on all subsequent playthroughs. And if I were in the author's shoes I would replace the promised meta-prestige layer with a firm ending, but I'm looking forward to them proving me wrong in future updates with whatever they still have up their sleeves.
