This is a small demo to showcase the bugfixes and options that have gradually accumulated over the last 3 years.

It only features Emerald Hill Zone and Death Egg Zone. I highly reccomend checking out the options menu, thought the default options should lead to a fun experience as well.

This rom hacks' original goal was merely to add time travel into Sonic 2, but it has since evolved into a very customizable experience with influences from Sonic 2, CD, and 3K.

Features:

• Time Travel: Time Posts from Sonic CD can be found around levels, and work as you'd expect them too. Badnik Generators can be broken in the past to make Good Futures, and Time Stones can be collected in the future. Collecting a Time Stone in a Good Future makes you turn super, and freezes the in game timer! There are also options to choose different methods of time travel that make it easier and more convienent, like replacing Time Posts with time travel monitors, or disabling the cutscene that appears while time traveling. Or you can disable Time Travel altogther and just enjoy all the other options, as if it was just regular Sonic 2 without time travel! I won't judge :3 You can also skip straight to the past, bad future, or good future at the title screen, by holding down A, B, or C respectively.
• Characters: You can play as Knuckles, Metal Sonic, and Amy as well as Sonic and Tails! Some characters can also have their artwork, palettes, and/or movesets modified by the Character Style option, which lets you play as Sonic CD or Sonic 3 styled Sonic!
• Sound Options: You can choose to use the jump and roll SFX from Sonic CD, or the classic ones used by Sonic 2! And you can choose from multiple music playlists, letting you use different music, from custom music and remixes made by generous people, or songs from other games like Knuckles Chaotix! You can also opt to turn off music and/or SFX if you just want to enjoy the music, hear the SFX without music, or just prefer the sound of silence uwu
• Camera: Sonic CDs' camera can be enabled or disabled, letting you enjoy the extra camera distance provided by Sonic CDs' camera system if you prefer that.
• Items: You can opt to use the shields from Sonic 3 and Knuckles instead of the Sonic 2 Shields! And you can even use 3 brand new, never before seen custom shields as an option as well! They function like the S3K shields but have unique effects and abilities! You can also make all items random like they are in 2 player mode, or make only shields randomized; the latter 2 options allow you to obtain both the S3K and Custom Shields in one game, letting you try them all out at once!
• Layout: You can choose between the original Sonic 2 layouts, or new custom layouts that were made with exploration and Time Travel in mind! The new layouts have large, vertically oriented levels full of secrets and time travel oriented areas like in Sonic CD! They're also better made to work with the S3K or Custom shield options, if you choose to try those out. I think they're a lot of fun, I hope you'll like them too ^w^
• Metal Sonic/Sonic/Metal Knuckles Boss: Death Egg Zone has a new act, with a custom rendition of my favorite boss fight from Sonic CD! Race against Metal Sonic and get to the end before the laser takes you out! Or if your playing as Metal Sonic, beat Sonic to the finish before his spin jumps can wear you out!
• Credits: The letters on the credits screen can be knocked down by hitting them! So even if your not the type to read credits, you can still find some fun in it :3

Character Abilities:

• All Characters: Holding down the A button allows you to 'freeze' your time travel status, allowing you to avoid time traveling unintentionally, or maintain the time post sparkles even when standing still.
• Metal Sonic: pressing the A button lets you use 20 rings to become invulnerable for a few seconds, just like the Metal Sonic boss does in Sonic CD. Metal Sonic can also break spikes whenever he is invincible, again like in the original boss fight.
• Amy: Pressing A lets you use her hammer, her only normal means of attack. She can also do a high jump if you crouch and then hold a jump button.
• Sonic/Metal Sonic with an S3K/Custom shield: Double jumping lets you use the shields' double jump ability. Sonic and Metal Sonic get different double jumps from the same shields. Also, the Ice shield has a unqiue ability; holding B or C allows you to walk on water!

This hack has had a lot of changes made to it over the last 4 years, and I'm not the best at keeping track of things. If you want a complete run down of every major change this hack has, both in this demo and outside of it, this youtube playlist has all my dev log videos about Sonic 2 CD Remix.

For Funsies, here are some "Option Sets" you can try, to change how the game plays. They can really make you feel like your playing a different game sometimes, it's pretty cool X3

Faithful to Sonic CD: This one really makes you feel like your playing Sonic CD!

• Character = Sonic Alone
• Style = CD
• SFX = CD
• Timetravel Type = Time Post
• Camera = CD
• Timetravel Scene = On
• Monitors = Sonic 2 styled Shields
• Layout = New

Faithful to Sonic 2: For if you prefer Sonic 2s' style. If you go all out and change the layout to Old and Timetravel type to None, you'll effectively have vanilla Sonic 2s' Emerald Hill Zone with some slight tweaks X3

• Character = Sonic and Tails, or Knuckles
• Style = S2
• SFX = S2
• Camera = 2
• Monitors = Sonic 2 styled Shields

Mania/S3K: If you prefer Mania or S3K, this might be the option set for you!

• Style = Mania/S3K
• SFX = S2
• Monitors = S3K Shields, or Random Shields
• Layout = New

Robotnik Returns 2: Makes the game play more like my old rom hack from around 2016. Knuckles gets all his moves from that rom hack even!

• Character = Knuckles or Tails
• Style = RR2
• Player Physics = Faster
• Playlist = US

Maximum new stuff: If your tired of seeing Mania, S2, and S3K get rehashed over and over again, this option set might ease your pain a bit. Great for seeing all the newest and most experimental stuff all at once!

• Character = Metal Sonic or Amy
• Style = Max
• Timetravel Type = Monitors or Time Machines
• Timetravel Scene = Off
• Monitors = Custom Shields (the 'ball monitor'), or Randomized Shields, or completely Randomized items
• Layout = New
