I found this really weird glitch while running the game. Here is the video link: So basically in the room with two moving targets, the wall at the end is automatically unblocked. Then, in the underwater targets room, the door unlocks after hitting only two targets. No idea why this happens.

This has happened to me multiple times, and I think it has something to do with how low I hit the bottom target in the first room with the targets.

If this glitch can be figured out, it could save a decent chunk of time.

I figured it out, you have to hit the top part of the bottom target
