As noted above, the June 16th prototype has a different stage select that's enabled by default. This replaces the Japanese version's stage select, which can only select the first part of each stage.
There are also 8 extra scenes (if they can be called that) that can be selected.
Trademark symbols were added to certain graphics starting with this build.

The Cast Roll sign now uses its final, correctly spelled design.

This inexplicable change to the Super Finagler's lasers first appeared in this version of the game. If this was made to make the beam harder to see: Boo. Boo, I say.
Scene 3-1
The HeadCase in the Flying Soldier arena is gone from this point on in development.
Scene 6-4
June 16th
June 22nd
The separate power-up screens from the Japanese game were merged into one starting with this build.
Scene 8-1 / Scene 8-2
The biggest surprise, gameplay-wise anyway, in these prototypes are in these scenes. In addition to carrying the Pin Head and Spike Head, HeadCase carries the Super Head in the June 14th and 16th prototypes.
This is a most unusual addition. The Super Head doesn't appear here in the final English game, the final Japanese game, or even in the April prototype! It seems to have been added specifically for the localized game, then quickly taken out by the June 22nd build.
The June 16th script is a rough translation of the Japanese text. This and all other dialogue was completely rewritten for the June 22nd script, which is short and to the point.
The June 22nd script has an unnecessary line break in the second chunk of text.

The June 22nd text adds a high-larious pun to the last bit of text...
...which cuts off the first two letters of the line. Oops. This was corrected in the final script.
All three of Headdy's friends have more dialogue in the Japanese and June 14th/16th prototypes: One chunk prompting to take the training, two for confirming or declining the training, and one for failing to complete the training. Here they are, in all of their clunky, unedited glory.
The June 16th build keeps the Japanese text, while the June 22nd build is mostly the same as the final, save for "FIGHT!" lingering around in the instructions.
Almost every single character in the cast roll received a name change:

The June 16th build keeps the Japanese name for almost all enemies, except for the redesigned bosses and, for some reason, Funky Ronmell.
Headdy's helpers, Heather, and Dark Demon, on the other hand, already have their final names at this point. Smiley and Trouble Bruin would be changed by the June 22nd build.
Already depriving them of their individual identities, the four pink puppets are "Puppetons" in the June 16th game. This was changed to the less interesting "Townsfolk".
"Mons Meg" is known as "Castle Cannon" in the June 16th build.
"Funky Jeepman" changed to "Funky Jeep Man" because Jeepman is not a word.
"Gatekeeper" and "Nasty Gatekeper" are under the preliminary names "Space Keeper" and "Space Keeper 2" in the June 16th script. Which is odd, since with these names, the Ghostbusters reference isn't there.
Mr.Kiosaku, Under Soldier, and Jayron got to keep their Japanese names in the June 22nd script.
Through some freak accident, Honeywan I and Honeywan II became Honeywan II and Honeywan III in the June 22nd build. They were eventually given different names entirely.
The June 14th script is missing the American credits: In fact, the entire set of credits in this build is a severely truncated version of the Japanese credits.
Obviously, the June 14th script doesn't have the (IN JAPAN) and (IN AMERICA) headers.
Several lucky staff members got to use their full names in the final English credits. This isn't the case in the June 16th script or in the original Japanese credits.
"Game Producer" was shortened to just "Producer".
The "Enemy Programmers" job was shortened to the less descriptive "Programmers".
The June 14th script gives Koichi Kimura, Makoto Ogino, and Kaname Shindoh their own separate section of the credits. The final script combines them under two sections.
"Puppet Designer" was changed to "Character Designer".
"BG Designer" became the unabbreviated "Background Designer".
Because of this change, Koichi Kimura is listed in the credits twice...under two different romanizations!
The "Guest Designer" credit was moved after the Background Designer section.
The obviously misspelled "Soundd Creater" section was corrected to "Sound Effects".
"Music Composer" is properly pluralized as "Music Composers". There's more than one, you see.
The "Special Thanks" and "Public Relations" sections swapped places in the final English credits.
The Manager section was moved to where the Guest Designer slot used to be, and the section title was rewritten as "Director".
James Spahn was added under the Interpreter section, which was updated to the plural "Interpreters".
Max Taylor was upgraded from Product Development to a Producer, and is now under the (IN AMERICA) header.
The company credits were changed, much like the ones on the title screen. They also gained trademark symbols.
