Actually there was a reason why I called my game the way it is... Despite that the "real world" takes place in Japan, most of the main game takes place in the "dream" space and the lore of said space has influences from bunch of different cultures (as I wanted it to be like a psuedo internet world thing...), especially the "dream" space having a Polish-influenced lore (As "Sen Planszetka" is supposed to be a Polish translation of "Dream Planchette/Board" but with a "-ka" in the end to make it a more weirder name) and characters that are from different regions in the world. I also wanted my game to give off a very "aesthetically very weird and weirdcore ridden" vibe which I took most inspiration from Madoka Magica, some of Satoshi Kon's films (Perfect Blue, Paprika, Paranoia Agent), Cat Soup, Popee the Performer, Dreaming Mary, and mainly Yume Nikki (which is also where I got the inspiration for the naming convention from as "Yume Nikki" means "Dream Diary" in Japanese)... So yeah, as much as I wanted find another name I could title my game... I felt like "Sen Planszetka" is so far the most suitable name I can give it...
Speaking of which, originally the game was gonna be called "Velmentia", named after an area in the Ratchet and Clank game, "Planet Veldin", and the word "dementia", but I feel like that's too on the nose to the R&C games and I wanted my game to be a whole different experience from it...
Anyways thanks for the suggestion and I'll try add something oriental in my game soon!
