It's great that you're adding elements from your own culture into your game. That will absolutely help make it feel more unique from other games. I love when indie creators put cultural references not derived from Japan, the U.S., or Europe in their work. I recently played "A Space For the Unbound", which was made by Indonesian devs, and it absolutely shows.
Also, I'm glad that we'll be seeing more of Kalia in the future after this current game. Your approach to worldbuilding is good, as well. It's smart to keep the scope of the first game small and slowly expand from there.
