That taptap dev info on the game has misleading information. Its only available in 2 regions right now. and they put arena breakout's trailer for the video about pre registering on the game.. Those people who taken part in the closed beta for Auroria knows that its not similar to palworld.. Auroria takes place in different planets (or stars?)  The small creatures are chuchus, they are the inhabitants on the first planet/star you visit. Most of them do not fight, they provide assistance such as item finding, or tips and hints in the game.
