0:00 the start isnt very easy to sightread, Maybe replace the yellow pad with a red one and Angle that one block, or make the first jump a pink pad. 0:07 that launch is very sudden, Maybe add a yellow pad there? 0:11 that transition is very sudden, Maybe replace the first robot jump with a blue pad? 0:14 that yellow orb shouldnt be a buffer only, Maybe shorten the platform? 0:16 people might not know how that part works, Maybe have some Lines to show which orb is connected to which portal? 0:18 that platform is very low down, Maybe zoom out the screen a little, or add an arrow? Thats all, hope this helps!
