I really like this game! I've played some other similar game that had multiple types of undo, IIRC, but this is a really nice realisation of it (that also fits well to puzzle script's constraints, which I appreciate !). "Over There" really stumped me! Some really nuanced behavioural differences. Some of the later levels I kind of stumbled through by, not so much thinking of what exactly would happen, but more permuting various elements until I stumbled across the right behaviour. It does seem there might be room for a bit more level design here.
I'd really like to add this to the puzzle script gallery - If you're interested in this, the one thing I'd request is either a puzzlescript.net (aka GitHub) hosted version of the game, or for you to add a link to the source code here (the gallery is meant to be a exhibition of puzzlescript games that I think are good, but it's important also that people can see what's happening under the hood so as to demystify puzzlescript a bit, should they wish). Either way, wonderful game :)
Sorry for the long wait. It took me a while find where I put the source code for my game. Please tell me if I missed any step, I'm still new to this.

Thank you - I just added it to the gallery. I'm happy that my commented prompted you to find where you put the code. 😄. (pro tip: it's possible to reclaim source code from the standalone files if everything else gets lost: https://www.puzzlescript.net/Documentation/extract_from_standalone_html.html ) - should be here https://www.puzzlescript.net/Gallery/index.html (you might need to force-reload). Let me know if there's anything you'd like me to tweak about the listing.
Thanks for the nice game again!
