You don't really need my save. I'll include it anyways but just go here (change 'markr' to whatever your PC name is of course)

C:\Users\markr\AppData\Roaming\Godot\app_userdata\Ex-Zodiac

Open the save_EA file

Replace all for:

"complete": false,

to

"complete": true,

That will unlock all levels

trainer is fixed.

Sorry but there still is an issue.

So the invulnerable and health cheats worked for levels 2-5 this time (as well as level 1 like it did before) but not in level 6. In this stage you use a different vehicle, a hoverbike riding down a highway while in all previous normal stages you are in a fighter jet similar to the StarFox Arwing

So my guess is different vehicles have different addresses for such things because in the bonus stage for level 1 where you are flying around Space Harrier style and not in an Arwing, the cheats don't work there either.

Long story short:

Arwing in stages 1-5: Cheats WORK
Stage 1 Bonus area (named Cyberspace): Cheats do NOT work
Hoverbike in Stage 6 (named Xenon): Cheats do NOT work

I do not know if there are more unique vehicles later in the game
