Your red enemy cubes don't teleport you anymore of another object touches it, only if it touches YOU then it will teleport you!
If it doesn't seem to work or if your particles are too slow, increase your particle speed and maybe increase "power" from your script.
1. Do this for spawning objects, so your Shoot.cs script.
2. Create another Rotating cylinder and animate it to spin faster, make this inactive.
3. In your shoot script you are going to make two public gameObject variables, one for slow rotating cylinder and one for fast cylinder.
4. Enable the slow one (and disable the fast one) only when you're not holding left click.
5. Disable the slow one (and enable the fast one) only when you're holding left click.
