These are the notes I have for it:
The challenge of this hack is to get through each act successfully, without being caught by Him in the process. After the first 12½ seconds of every level you will be warped to an alternate dimension where rings work in reverse, badniks are invincible and, if you stay for too long, He will get you. The only way out is to break a monitor in this warped dimension, whereupon you will be sent back to whence you came. However, after your first warp and return, the time until your next warp is uncertain. It could be 20 seconds, it could be in 3. Just be sure to return before the end of the level, because there's no escape until you do.
From the title screen you can choose to start straight from Green Hill Zone and go through the whole hack, or be taken to the Zone Selection screen. From here, you can choose any of the zones available and see your best scores from each act that you have previously played. Score works as normal in this hack, except when you are trying not to be caught by Him your score will be reducing every second until you manage to escape.
