The fix...
Ok. I've read all your comments and here are the replies:
The first level should have lots of switches, and this is the only level that does. Zone 1: The Gate is the entrance to !!!'s World of Chaos, and there is a tight security system. Unfortunately, Eggman found a way to sneak into The Gate and forced his robots to guard The Gate even though The Gate is already guarded by the doors. Eggman wants to take over every world to gain more power. !!!'s World of Chaos is his 2nd target. Sonic's World was his first.
The Gate is a one-way only zone; there are no other paths except the ones you should go through. The level varies with the difficulty level you choose:
Easy- not much enemies; except for the end
Normal- many enemies; same number at end
Hard- totally lots of enemies; same number at end
Very Hard- same number of enemies as hard, but when you get hit by an enemy, you can't get your rings back
Ultimate- same number of enemies as hard, but there are no rings at all in the level
This is the only level that would have no other paths to explore, lots of buttons, and lots of enemies in one room, but the other levels would have very wide open areas for Sonic to explore. Everything is already planned out.
There are turrets only in the hard difficulty. In easy, there are no turrets, but detons in end.
Each sector is 200% bigger than the original. I think the size is better too, but all the ceilings' height are the same. Good thing: When you break a breakable wall, the rubble falls (the wall collapses). All the enemies and the scenery has been changed.
Because of the overall size of the level increased, the size of some switches increased.
Just to tell you, the huge sector at the end of the level is called "The War Zone" because of all the robots. Remember, use all monitors wisely and use them at the right time.
