I think my favourite thing about the game was hearing the zombies groan for cigarettes. Very entertaining and did a nice job setting the tone. I immediately wanted to play more because of it. The CRT effect was cool as well as the blood effect from the zombies hitting you.
It was a bit hard to understand where the zombies were, and where to find pickups. It didn't feel like there was a chance to evade zombies if I couldn't zonk them before getting bludgeoned. I still appreciate that it's not impossible to see without the flashlight. I couldn't tell if the escalating flashing effect was affected by smoking, the light, the zombies, or something else though. I had a hard time navigating the environment after 2-3 minutes because the effect got overwhelming quite fast.
The other effects in this are quite fun. I really enjoy the idea of some pissed off dude looking for cigarettes and fighting off a horde of nicotine-addicted zombies with nothing but a flashlight. It's a fun concept!
