I bought the Expanded version to show support, because you're one of my favorite devs, but I will say that I think it is a bit early in the game's cycle to be pay-gating features. The initial release felt very concept/Alpha, and these QoL changes are welcome, but not a substantial overhaul. Of the two features pay-gated, the Sandbox mode is definitely an understandable one, but the body proportions feel a bit rough to gate, especially given that almost all of your other games go to those sizes or larger for free.
I know things are really tough right now for adult game devs, which is again why I paid up anyway, but I personally think this title needed at least one more revision with some gameplay variety before splitting into paid vs. unpaid tiers.
