Win 10 64b PC Ati X290. Some observations and opinions.
-Graphics artefacts and clipping issues. Beating things on the bridge makes the loot fall right through them so that makes sense.
-Shop interface is wonky as Timeslice already mentioned.
-When the sheriff dies, all friendly NPCs outside seem to die with him. (multiple youtubers had the same happen) NPC in general are too vulnerable. The one in the hospital was surrounded by zombies when I spawned in and he was dead before I could get a shot off.
-Combat barriers in dungeons (cave, church, hospital) are tricky. If you don't fully commit or run back out as soon as you spawn, you run the risk of being locked on the outside with no way to bring the barrier down. Reloading seems the only way out.
-You can enter and exit dungeons for infinite ammo if you so wish. The pistol isn't all that anyway but it's probably not intended.
-Beating panels off cars regularly ends with the panels dropping on top of the car with no way to get them off. Irritation diminishes enjoyment.
-Building placement is quite frustrating at times. Harvesting corn that was planted behind a tower is also quite the undertaking.
-Going back to the menu resets all options back to default.
-Seemingly unskippable intro. Less of a problem now saves work, but a bad idea for any game.
All in all an interesting little title. Keep up the good work.
