Usually known for their internal online and mobile games. In 2023 we get Dave the Diver and Lies of P which are non mobile single player games.
Tangentially is 2023 chock full of great games because the pandemic held up the development of so many studios?
It’s probably stuff being less “indie” than it appears on the surface. Both of those games you listed appear to have successful publishers, one behind Maplestory and multi-million (in USD) net income (also largest shareholder is investment firm, Maplestory NFTs). The other has more games (and significantly more DLC) on Steam.
That doesn’t really answer your question, well aside from saying money. Though there may be a deeper connection as well (shareholders having hands in everything etc)
