- In this level, you can do all of the abilities from the start, including sprinting. As a general rule you should sprint everywhere because it is somewhat faster.

- When you first get your gun, it only has two charges. Click the right mouse button(RMB) to bring the gun up to it's max of three charges to clear this stage faster.

-Piston Jump off of this platform and recharge immediately so you can shoot the platforms while in the air for a faster time.

-If anyone finds a way to skip a part of the moving charged platform please give me a response in the comments!

The piston jump exploit can propel you past level 4 since it is completely vertical from this platform:
and a very small timeskip on level 1 if you can aim while moving right here:
This is really tricky, but if you can complete it sucessfully once you can get the hang of the timing it becomes quite easy from there.

To do this, you have to shoot the piston and then jump while the piston is still moving up. It sounds simple, but is actually somewhat hard to get the timing right.

This can be quite tricky due to the problem which is if you press too early you will be stuck inside the pistoon for a brief period of time and then promptly teleported out of the piston. If you do it just right, you should be launched into the air.

Sprinting is an essential part of speedrunning this game. Here are some tips to maximise the amount of time you can be sprinting:

You can start and stop sprinting in midair, allowing for extreme movement control in the air.

You can't sprint while activating a platform, but you can sprint after you used the platform in midair.

Let me know if you have any more tricks for any more of the levels, as I'll try to update this somewhat often.
