Cool to see you're still working on this! A couple things though.
I can't seem to progress after the first level. Like with the jam version, it looks like the game still has the issue where you have to be precise to open the last portal with the blue square after rescuing the hostage. I couldn't seem to get it to work at all this time, though. Unless there's something I'm missing?
Also, I noticed the downloadable version you uploaded is just the HTML file you use for the browser and not an executable.
