i beat the game and got game over as if i had lost

Here's the instruction - click on the red dots to destroy them and don't let them get close to the player.
However, I think the collider of the player is too big. Maybe making them smaller until they fit with the eyes. Apart from that, the music is EPIC. It's not a bad game after all once you figured out the instruction.

without any instructions this game is basically unplayable.

No idea what's going on. You haven't even provided instructions and the inability to skip the intro is really annoying.
