i feel like an idiot saying this, but is this game discontinued?

anyone care to share their best tactic for survival? I'm doing just okay right now, not sure how to get better.

The game is extremely dark for me and there is no way to change brightness settings or anything. Compared to the screenshots and videos on the store page, it is extremely difficult for me to see things and everything is very dark. Not sure if it may just be my comps hdr or color setting but yeah....

Is GoG planned by chance?

Am i doing something wrong or is the achievement bugged? From what i understood you are supposed to deflect back the larva projectiles right?
