I did some work on this game in the past. I got a vwf inserted and working, I inserted a few lines of your translation just to see how it looked. I haven't looked at this game for awhile and probably won't unless someone wants to translate it.
Wow, your font looks great! Could you share an IPS patch for the font, please? Unfortunately my knowledge of Japanese is rudimentary so I can only translate very basic sentences.
I'd like to note that I was inconsistent with the name of the kingdom. Pufftop is not an actual translation but is what Tenkai was localized to in the English versions of The Legendary Starfy for the Nintendo DS. Tenkai is the name of Starfy's kingdom that is mentioned in Densetsu no Starfy 1-4.
Tenkai is a combination of 天 (ten: meaning sky, heaven or celestial) and 界 (-kai: meaning world or kingdom). This means there are various possible translations like 'sky world', 'sky kingdom', 'heaven', 'celestial world', 'celestial kingdom' so I feel I should have just left it to 'Tenkai' or 'Pufftop' in my video instead of Sky World.
Some other terms from Densetsu no Starfy that were translated in The Legendary Starfy include these:
*Stafy: Became Starfy. Media calling him 'Stafy' include like the movie poster in the Yoshi Theater in Mario & Luigi: Superstar Saga, official site links, Super Smash Bros. Brawl, the 'Baseball Cap', 'Wrestler Clothes' and 'Uniform' Stuff in Densetsu no Starfy 2. I believe Stafy and Starfy are interchangeable though, see this
*Kyorosuke: Became Moe.
*Rob-jiisan: Became Old Man Lobber. Note ラブ was romanized as 'Rob', not 'Lob' on the Rob-jiisan Shirt in Densetsu no Starfy 4.

I'd like to note that some of the Densetsu no Starfy playing cards
suggest what the genders are. The gender of the character Wotsaruto is debatable, however. Wotsaruto wears a bow-tie stereotypically worn by males, and in Densetsu no Starfy 3 Wotsaruto uses the word 'boku' to refer to his/herself, used by males. Wotsaruto's playing card is Queen though and some other female characters use Queen.
