Failed? Seems passable enough to me. Good, even.
That said, try to work on the audio a bit. And add subtitles. And background music.
This game has potential, so I hope you'll keep working on it.

top tier 5 fps gameplay

it was a fun ride man. there is a playable game.

Cool idea, but the SFX audio level is a real problem, I know you don't have a lot of time, but this is not just a small detail, as it's absolutely very very loud, and if you lower the volume, then the voice is indistinguishable. The levels in the tutorial part are good, and the time slowing is an interesting mechanic
