As always, you prove yourself to be a great puzzle game designer! I haven't finished it yet due to lack of time, but I think I'm getting close to the end. The main mechanic is very fun, and the puzzles have a nice difficulty curve.
I'm not a huge fan of the narrative setting (it felt a bit random to me) but I really like the characters. I probably would've avoided pixel movement, though, since the core mechanics are tile-based. The graphics in a few spots (windows, icons, and fonts) could also use some polish, but for a game jam, it's more than fine as is. Great job as always!
