My first attempt

I'm liking these edits. Can you design CPZ for me? ;D

 

That CPZ palette looks a lot like mine... I'll probably be changing mine, though.

 

I like the colour scheme, It is a nice dark blue shade which doesn't clash with Sonic or with other background objects.

I also liked the layout as well. It rarely feels bland, which is a problem most first attempts suffer from. It always feels like if there is something on screen. Be it an item box, an enemy or some spikes. There are also no cheap shots or deaths which made it rather enjoyable. It's a bit buggy at the moment, but I feel potential in this hack.

The only thing I find weak at the moment is the no-screen box, which hurts you. It would be better as a Robotnik icon.

 

They were very simple, and to be honest, I loved it. Yet again another fresh level layout :P

 

I shot up from below to here:



Went into the yellow and black striped tube you can see. Now I'm stuck out of the top of the screen walking backwards and forwards.

Also:



If you jump forward at this point and land on the part where the pipe flattens out (which I did first time) you end up back near the beginning of the level. To fix this (if using SonED) I would change the layer Sonic is on when he enters that area so the pipe is solid and change back when he has passed it. This may be intentional though.

Other than that, love the layouts! It would be great to see this hack being taken futher!

 

I really like the palette you made.
