Not sure if works with any object. "Spawn delaying" (pressing opposite direction for) 5 times can enemies not appear / spawn.
For comparison:
- Object spawn avoidment: 5 * opposite direction = -10px in air, much more on ground (next time: 2-3-4 frames later)
- Object spawn delay: -0.5px in air, -1.5px on ground each time (next time: 2-3-4 frames later)
- interrupt juggling: -3.5px~-4.5px each time (since you are zigzagging)
