Finally had the chance to go through a few of the paths and fixed  some  syntax-errors related to the Harlowe -> SugarCube engine change. Version 2.2.2 is now the official release version that everyone plays using the browser, as well as the only version that can be downloaded.

2.2.2 in a nutshell, compare to 2.1.1:
- Save and load your game

- Difficulty setting for chapter 2 (in config menu)

- Toggle images on/off at any time during your game (in config menu) rather than selecting it only once in beginning of the game

- Can no longer "disable the cheat mode" i.e. you can always press the "back" and "forward" buttons

- Changed Twine engine from Harlowe to SugarCube

- Centered all images  and put them at the top, for a more consistent experience
