Sonic Chaos - Turquoise Hill Demo

Average User Rating:
  • Sonic Chaos

    Sonic Chaos is a fan game and re-imagining of the 1993 Sega Game Gear and Master System platform game of the same name. Based on the current style of 2D classic Sonic games inspired by Sonic Mania, Sonic Chaos updates the 8 bit visuals of the original and adapts a play style more closely resembling the classic 16-bit games. The game has been in development for almost an entire year, of which the last 3 months was spent building a brand new engine from scratch. Sonic Chaos uses this new engine, Crimson Engine, and with it we've strived for classic Sonic gameplay accuracy.

    Since the initial release, even after only a few hours; we've already gotten tons of feedback and bug reports. We're so glad to see this many people enjoying the demo, and we'd like to make it the best we can!
    So even though SAGE has begun, we'll be releasing plenty of updates during the event, stay tuned!

    "Absolutely amazing."
    This has got to be one of my favorite sonic fangames ever.
    The game looks absolutely astonishing: The custom sprites are absolutely beautiful (ie the sonic mach speed sprite), The gameplay is on par with mania, and the music.
    Oh my GOD the music is fucking incredible.
    While there are some cons (lack of collision sometimes, spikes that you couldn't see coming due to going fast, etc) they are absolutely minimal compared to the pros. This is an incredible sonic fangame- hell this is an incredible game in general; and it's only the demo!
    Overall: amazing game, on par with mania. And it bops.

    This is great for being able to pull so much out of Sonic Chaos and turn it into something that really feels like it could belong in Sonic Mania. On that note, I wondered if it would be possibly faster and easier to just mod Mania with the Chaos levels like this. This felt much more hand-made , which definitely has a genuine feel, though there were an instance or two where I ended up in some walls. I personally loved this, though since it's using a custom engine, I'd love to see maybe some additional characters or character mechanics in the future, something that sets it apart from just being something that could be just a mod for Mania. Sonic Chaos was a pretty short game so I'm sure there's a lot you could do with it in making a more modern adaptation.

    Hi Mr.Potatobadger, how are you getting on with this, any progress updates since August? Is there any where other than here where we can follow development?

    So, I first heard about this project back in August, downloaded version 1.2 of the demo, and promptly forgot about it until now. So I finally got around to playing the demo, and version 1.3 and I have to say, overall, amazing work! I did notice a couple issues, overall, though. First are the few areas where Sonic clips through solid ground, which the recent posts before mine have mentioned in detail. Secondly, though, is an issue involving the frame cap implemented in version 1.3 of the demo. While playing version 1.3, I noticed the game did not scroll as smoothly as version 1.2. I use a 75hz monitor and I'm guessing the frame cap hard limits the game to 60, since 60hz is still pretty much the most common display refresh rate. This causes the game to look jittery on my display, as opposed to 1.2 which was buttery smooth.

    I don't know how often the dev team reads the comments here, but going forward, PLEASE make the frame cap a toggle-able feature, or a frame cap that matches the current display's refresh rate. While the feature is fine for those using a 60hz display, there are an increasing number of people using higher refresh rate displays (75hz, 144hz, 165hz, etc). Otherwise, great work, and I'm looking forward to seeing the next iteration of the project.

    Is There Any Way This Could Be Made Compatible With Android?
