A generic Sonic 1 ROMhack is a ROMhack which mainly focuses on level design. It's goal it to make the levels feel fresh, even though you're playing through the same zones again.

The hack currently is WIP and still has a quite a few bugs, but they'll be ironed out in the SHC 2017 build (if there is a SHC 2017 build). The main reason why I'm releasing it a bit early is because I don't have any testers and I'd like critisism on the level design, since it's the main focus.

The current levels include: GHZ1, GHZ2 and GHZ3.

Crush Dr. Eggman!

After Dr. Eggman's defeat in Sonic 4: Episode II, the Death Egg MK II has crash landed on South Island.
Eggman, who's still recovering from the crash landing, immediately recognises where he landed.
"Wow, the graphics really are a lot worse here", Eggman said upon looking at the pixelated trees.

So, using his knowledge of South Island, and improving on his plan from last time, Eggman builds his new and improved base on South Island.
It's up to Sonic to stop him (again)!

Help with fixing bugs

NOTE: if you want to record footage of this WIP hack, you're free from doing so, but it would be appreciated if you'd wait for the SHC 2017 build (or if I don't fix the bugs by then, a later build in this thread).

ACT 1: I do not like how GHZ1 opens. It is too dangerous and too difficult for the very first action a player takes in the game. At least you added the spindash.

Also, the area below the broken bridge? That is too mean for the first level! You need to ease players into the game and ramp up difficulty appropriately.

Everything else in that level seems alright, though I had quite a bit of sprite flickering when breaking down walls leading to lots of items, objects, and enemies.

ACT 2: The underwater stuff was a nice change of pace! But some of the spike placement was a bit dickish. Also, having Chopper jump out from an area that is not a bridge felt very wrong.

On top of needing to fix the graphical issues with the water graphics, you should look into having a different background for the underwater areas. It doesn't look right the way it currently is. This can be achieved pretty easily with clever use of the chunks to obscure the main background.

Also, that platform you land on after that big automated sequence at the start shouldn't fall out under the player's feet into a pit of spikes. That's just mean.

ACT 3: Aside from a sequence involving jumping across moving platforms above a spike pit, I've got no real issues with this stage.

Liked what you did with Act 2 and Act 3 but Act 1 was not as good. It was too hard for a first level and it had dickish bottomless pits. Rule of thumb on a Sonic game is to let the player know when bottomless pits are and use em sparingly.

(Thanks for the feedback, by the way)
