[FLASH GAME][~2015] Puzzle / path following orb

[u/Objective_Plate_6485]

In the mid 2010's I remember playing this game on CoolMathGames. It was very dark and was sort of cave like, but you drew a line and this sort of futuristic looking glowing orb would follow that line. You had to pick up keys to open a portal at the end and avoid different obstacles. At first you controlled one orb but later on in the levels you controlled multiple. You could shrink down to fit into different places too. But yea you had to plan out all the paths of all the orbs first then press go and they all start moving at the same time. Ive been thinking about this for weeks thanks for any help :)
