Elliot's first dream, Splash Garden is well-kept garden showcases powerful fountains, floating water bubbles and a flower clock that chimes the hour. Not only is it close to a lake, but a trip through the watery caves takes you to treasures hidden in its depths.
SG1's infinite is pretty straight forward except for the fountain (where you need to make a big enough paraloop while maintaining your link), and the two randomly floating Memus.
Below is a video showing a complete run of the infinite.
SA.net member Lance Way found, as he called it, a 'silly' exploit, that abuses the 15 minute time limit to potentially add 30k to the SG1 score. Check out his detailed post for more info, though note that this technique is currently not allowed for scoring here (though out of interest, the current records are SG1 - 136970 (50k pre-mare1) and SGT - 653000)
