I want to know how to do advanced math.

Will the game be in more languages ​​or only in English?

i load the game and then i cant move and all the types of HUD are showing and im in the sky

Not sure what your financial situation actually is, but sometimes it's all it takes for someone like Pewdiepie (who still plays games apparently, see his latest video), Markiplier, Vinesauce, etc. to play the game to get it popular, at least for some time. Or hell, work with MrBeast to do a MrBeast challenge in Plasma. Not sure how feasible it is (unclear if you pausing the development is just a precaution or are you on the verge of bankruptcy), but sometimes all it takes is for some e-celeb to showcase ...

I m reading some people saying this game was abandoned at an unfinished state, is still worth buying as is?
