Well, Birdland is a full level (and not one accessible from the main progression), so you could just give it its own video, or else a combo video of it and Psych3. Would also give you an excuse to mention the OMF statues. Good job on complaining about the transparency effect and showing off the extended ricochet effect. I had forgotten all about those crazy Acc Belts, so it was nice to see them in action. Just a few small notes, more like thoughts than actual corrections:

• You're right that the potion is animated, but no food pickups are. So why assume it was supposed to be a food pickup at all? The animation set it that it's in is very general, containing powerups, ammo crates, and all sorts of stuff besides just food. Labrat does seem like a plausible place for it to have gone, though.
• Do you really not have resolution options? My 1.00g has more resolutions than in the final game. Weird!
• You wondered why there are old toilets and computers sitting around: probably because much of its visual style was based on New Junk City from Earthworm Jim.
• Airboards do make additional appearances in Battle3 and Treasur2.
• Speaking of Treasur2, if you open its .lev in MLLE, you'll notice the old-style hooks are still in the tileset for that level, even though they were replaced with the wider ones in every other Labrat level.
• In fairness to Epic: the only ice ammo in the whole first episode is in Knight Cap, in one of three paths you may choose to take, and even that only if you're Jazz. It's not a foregone conclusion that you'll be able to freeze the robot boss. That said, it is almost certainly a bug.
