Sonic Time Twisted
From Sonic Retro
Sonic Time Twisted is a fan-made attempt, headed by Overbound, to make a new game that borrows some key elements from Sonic CD, including time travel, to make it one of the more unique Sonic fan games out there, while still being very true to the classic Genesis/Mega Drive games. The game has been in development since 2006, though since then, Sonic Time Twisted went through a total revamp twice, so as such all demos are based on various older builds of Sonic Time Twisted. The game made a comeback at SAGE 14 Acts 1 & 2, and is expected to be finished within the coming months.
The storyline will take space through a number of cut scenes through out the game similar in style to Sonic 3&K or the few scattered around in Sonic CD. Not too much detail has been given yet but it can be said that it involves Sonic, Metal Sonic, Dr. Robotnik, the Time Stones, Chaos Emeralds, and mysterious UFOs.
Sonic Time Twisted is a Game Maker based game, currently being programmed by Mercury using his very accurate AeStHete engine. Older builds used Damizean and RougeYoshi's Xmas Gift 360º engine. The gameplay parallels the Genesis games using similar level design which includes a large number of gimmicks for each zone. The game also grabs elements from Sonic CD, including time travel in two time zones and the time stones.
Only 4 zones of the current version of Sonic Time Twisted have made it into a playable form thus far. Note that they used to use the "Round" notation from Sonic CD, with Zones as the individual levels, but it has since reverted to the Sonic 1 style Zone/Act notation.
Originally the game's soundtrack was composed by LarkSS, but due to various reasons, he became unable to continue making the music shortly prior to SAGE 2010. The new version of the soundtrack is being mainly composed by Zach Hinchy, though there are a few tracks from the original incarnation being carried over (such as the theme of Perplex Puzzle Past). The SAGE 2010 demo features the new title theme and the Perplex Puzzle Future theme from the new soundtrack; additional finished and work-in-progress music from the soundtrack can be listened to at the soundtrack repository. Upon completion, the soundtrack, with the title Dueling Ages, is intended to be formally (but still freely) released as a downloadable OST.
Note that all of these screenshots are outdated as of the 2010 switch to Mercury's engine.
