Sonic bounces around surprisingly fast. The lack of Spin Dash makes the strategy a bit different from that of Sonic 2 and Sonic 3 & Knuckles runs, since preserving your momentum becomes a lot more important. However, this doesn't prevent the author from achieving crazy velocities even with such a significant limitation. In this run, the game is completed without collecting any emeralds.
This is the eighth run of this game, improving on the previous effort by 00:03.19 (of in-game time), primarily due to higher optimization.
To see a movie of this game that doesn't take advantage of zips, watch the "no zips" run by Aglar.
