1. you can do that by sliding. then to gain back speed, do a short longjump
2. the eggcops (which are called eggopps btw) dont have a regular speed intentionally. they follow the player's exact path, thats why they seem to teleport and fall off the map, thats how i coded em
3. might add that in the next update, and if you mean joystick for mobile controls then yea ill add that too most likely
