Play the game without sounds, just put your favourite music on the background and do your best.

Post void is a short Roguelike game with limited options, here are the perks you should take depending the gun of choice:

Pistol: it becomes obsolete as soon as you enter act 2, so pick whatever.

Shotgun: Bigger Clips, Reload speed

Uzi: Rubber bullets, Reload speed, Bigger Clips

Knife: everything not bullet related.

ALWAYS PICK EXPLOSIVE AMMO.

The difficulty relies in not having a seizure irl while playing
Take a rest whenever your eyes are tired,
Once you grow acostume to the you should get to act 3 in 2 hours or less.

You will beat the game if you play it, not reading guides.

No sé por que hice la guía en ingles, me volé jugando esta wea y me duelen los ojos.

En resumen, juega hasta acostumbrarte al gameplay LSD.
Creo que es más disfrutable si pones de fondo la musica que te gusta y le quitas el sonido al juego, en 2 horas te lo pasas.
