the title screen isn't completely finished either (still need to add some clouds n stars, tails flying w his plane in the back, a big planet i just forgot to include, and ofc sonics animation) The title screen intro sequence is just one of the concepts for the opening and it still needs to be cleaned up A LOT. but all n all this is still a pretty solid idea of how it will look in final. offtopic but i really like how the logo turned out.
If it's any correlation i do want to go for a sorta vaporwave 80s aesthetic for this game if you couldn't tell by the pink n blue grid speeding at the bottom of the title.
