Sonic Chaos - Turquoise Hill Demo

Project Overview

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!

I've played the original Sonic Chaos, and as easy as that game was, I found it incredibly fun and a good game to be one of the first games from the series I played. Unfortunately, I don't think the same about this game.

The level design for the first act of Turquoise Hill is okay at worst. At best, it feels like Sonic 1. Act 2 though... I wasn't sure where to go -- the stage kept forcing me backwards along the path I came, and in other parts it wasn't clear where to go. There aren't a lot of enemies there, either. I nearly received a Time Over before I gave up. The Zone hasn't got any truly memorable sections, which is a shame since I remember a couple of sections from the original, even though it's been years since I last played that game. I would've much preferred a straightforward port of the original's layout. It's been like 20-30 minutes since I played this game and I can only remember the areas of the second Act that I had to run through more than once, and maybe another one or two.

The look of this game is alright. The pixel art is impressive, and the spritework is really skilful, but I never liked the aesthetic of Sonic Mania. Arguably a personal preference, but I feel it didn't do justice to the original game it was based on and simply played on nostalgia for Sonic 2. Sonic Chaos had its own distinctive style, and I feel it would be way better if you remastered or even just touched up on the original's look for the sprites. The landscape and backgrounds are really pretty, although the ground and walls look a little too flat and shiny. The music really fits the Zone, though!

I'm sorry if I sounded harsh, but I really want to see this become the best it can be. I don't intend any hate. I'm excited for any new updates and demos, since Sonic Chaos is a game I love, and I wish you luck with it. Thank you!

This was amazing! There were a few collision errors, like how in the beginning of Act 2 it'll have you randomly clip through and if you don't do anything and youre at the right speed, you'll zip right through it, but they're minor and don't exactly make the game any less fun. I hope you continue to work on this, it is great, and I'd love to see more of it!
Not sure if this has already been mentioned, but there's straight up missing terrain in some parts of the map, including here by the exit of one of the tube thingies and also just above a set of sideways spikes somewhere in the first level.
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.
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?
hi my name is sonic safi im a youtuber and im intersted on your work doing sonic chaos when i first saw the trailer i was like "mmmm ok....." after that you still doing it u have remarkable friends and followers supporting u and your group amezingly u guys have a good day and night.
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.
I love this game! it does feel like i am playing a sonic fan game using sonic worlds though.
Just made an account to compliment you on a fantastic demo! I thought I was playing a insane mania mod until I finished and seen its a different engine. Very impressive! Sonic controls just like the classics and mania and it felt completely normal to just pick up and enjoy without adjusting to weird physics. The activated tree climbing things were very cool and very fluid. First act was perfect. The second act was good but it threw me for a loop :emoji_laughing:. I instinctively just wanted to go right and after going left for a while and then descending I started second guessing myself a lot. Overall tho this demo is fantastic. Alot of other fan demos or submissions tend to lack a natural flow in how the level progresses and the artistic aspect is always empty or over crowded. This was a perfect balance. Cant wait to play future levels down the road.
This should become official, and then the art at the top is the home menu icon. Sega's making fangames official now.
I´ve discovered two or three bugs in your Awesome project, they are in that short video.
