I dont know enough about the drop dash to know how it will be utilized the best in speedruns tho. If there are speed shoes, get them, even if you need to backtrack. If you enjoy this game then also play games Sonic Mania Edition and Super Sonic and Hyper Sonic in Sonic 1. Use three fingers on three action buttons to spin dash the fastest (you need 7 presses). Sonic 3: Angel Island Revisited - speedrun. This game is released to: PC, Xbox One X, PS4, Nintendo Switch, Nintendo 3DS, Mobile Devices (Android and iOS) and some Smart TVs and Chromecast/Apple TV. Remember that you can adjust your jump height depending on how long you hold the button, this also affects the momentum of the rotation tricks. Sonic the Hedgehog Mania 2, (also known as Sonic Mania 2 or SonicM2), is the sequel to the game Sonic Mania which was released for current gen systems. While going fast jump on upward slopes to use them as a ramp. Jump on downward slopes for even more speed but less height.

You can use this rotation system in creative ways such as using loops as boosters (jump from top left corner to bottom left and roll) because being upside down in the loop makes you jump downwards and redirect your jump momentum into the slope and the roll. The opposite would be true, but if you have enough speed on upward slopes you can counterbalance the pushback of jumping 'backwards' and redirect the momentum upwards, making it a ramp. The Sonic 8 is a multi-game speedrun of Sonic The Hedgehog 1, 2, CD, 3, & Knuckles, 3D Blast, Spinball and newly added Sonic Mania. If you are on a downward slope you will be tilted clockwise, making you jump 'forwards' which gives you more speed but less height.

It has a system where depending on your angle (which rotates with slopes) your jump momentum will change.
