With the way I developed the game, I never intended for a web build, so it's a limitation since unlocks are not tied to save data, and instead persistent data. You can however unlock all the gallery with the unlock code by becoming a supporter, or running through the game again on your new platform.
Unfortunately, because I reworked the UI and added accessibility for the visually impaired, some saves no longer work, but some do.
Because of this fact, I made an "Episode Skipper" you can toggle on in the options menu to skip to the most recent content quickly, either via a pre-defined save, or craft your own via choices. It's the best I can do.
Android is a little different. You'll need to download an app that lets you browse the internal files of your device, then navigate to the game, make a folder called "saves" and put the saves in that folder
