Devlog and thoughts:
-Made a new title card for levels.
-Found out how to make Sonic be able to walk out of the screen at the end of a level.
-I failed to connect the paths on Cobalt Capital the way i planned, so i decided to go further with the refe
ence and make 2 goals instead. I guess i should make an Act 2 and an Act 2' later.-If i do that i'll probably have to create two bosses for CCZ. I was already planning to make two bosses, but i wanted one (Metal Sonic) to be fought by Sonic and Tails and the other (Eggrobo) by Knuckles in an alternate path.
I also looked at some tiles i've made a long time ago with a NES palette and changed them a little:
And about the vuvuzela badniks, i made them that way because i had puzzles and hazard setups in mind that would depend on them working that way, but i guess i can create a variation of the badniks that works as you say.
