Nice work! My favorite level was the one with the malfunctioning droid, good use of bespoke rules in service of telling a story. Only things that felt a little arbitrary by the end is exactly how the teleporting computers work, and which codes map to which keypads in the last level.
Possible bug: I finished the (last?) level but it softlocked when I stepped on the exit tile. Pressing the Boss Key somehow still worked, producing this ominous screen on return. I was able to save+quit with ESC and see the ending upon continuing. This is with the web version on Windows 10 + Chrome, FWIW.
