LEVEL 25

Well... We're here, solver...

Seems like we need 6 symbols to proceed past this point. Each symbol requires something you've learned from me throughout the past. It's time to show what you know. GOOD. LUCK.

1. usmmrazitaoisn (reverse in pairs of two)

2. Bring this level to the folder where it all began...

3. The source of the problem.

4. You've seen this one before. 0110100101101110011101000110010101110010011011100110000101110100011010010110111101101110011000010110110000101110011010000111010001101101

5. Maybe there's some kind of mistake in the image...

6. Alfa November November India Hotel India Lima Alfa Tango India Oscar November Delta Oscar Tango Tango X-Ray Tango

7. Once you've obtained every symbol, add a .txt along with the site that's been used for the audio. All letters are lowercase. Then, we'll finally make it into the void.
