Hi there, thanks for your great feedback! The option buttons will be bigger in the Ren'py version (especially so, for the mobile/Android players). Label/tooltips will also be added for locations in the Ren'py version update. If budget/time allows, the crafting/trading system will be improved too. Version 0.1 demo is a quick fix in Tyrano so that I don't have to update the assets separately in Ren'py later.
The gender/physical change is optional and is a small part of the game/specific endings in the later chapters. Players have to pursue a particular route to transform physically. It is entirely skippable.
