https://minilanguage.com/ is an interesting one to look at. There are exactly 1000 words in the total vocabulary. That’s Mini Mundo though. A second, smaller variant also exists: Mini Kore, with 100 words.
I started learning it too soon after learning Toki Pona and lost steam. But I agree with the design principles. They stem from the observation that Toki Pona, as fun as it is, is just too damn ambiguous for anything non-superficial.
