I'm so glad you'd be happy to make a sitelen Lasin version, thank you! I think as long as the main dialogue is translated, that would definitely be enough, yeah.
As far as posting to Playdate communities - in my opinion, as far as Playdate games are concerned, the more niche the better; the whole idea of the console is to be a little quirky and unusual, so I think the general community would definitely be receptive to you posting about the game! And ma pona pi toki pona is a really friendly place, don't worry - the #pali-musi channel is specifically intended for people to share their projects, so don't feel like you're spamming or anything.
And thank you for the recommendations for the Bitsy games - I haven't come across either yours or Soweli Mu before, so I'll be sure to check them both out.
