Well..Thanks a lot for writing a comment about my game.
I have explained about how to spawn the objects and rest of the things in the help menu.
Even I felt that the ui could be better,but as i am a programmer i dont know to design stunning ui's.. I have designed the ui's with my 2d ui designing knowledge!!
Check out my 1st 3d game - https://sands-arts.itch.io/tint-revamp
Again thanks a lot for writing a comment.
