On some of the more mechanical puzzles (especially the hydraulic lifts it would be REALLY helpful if there was a "test" button to see what will move and how. For instance, it's not really clear that all of them will move at once, not one at a time. If you still want to keep difficulty up, make the button disappear after the first/only use.
And I'm still not sure how the first Steve's carrier birds puzzle can consider their weight/loads even when it seems to clearly NOT be.
Awesome game! Here's hoping for a full season, or at least on-going sequels! GREAT story and GREAT ending - kudos to Graham!!!
