Been playing this for quite a bit now...I dunno if anything I have to say has been said already or not.
1. Mannequins: Okay I eventually found out that simply hitting them easily gets rid of them, fine...but, it does seem like a new one spawns every day, or right after booting up your save...they're not scary anymore, just...annoying. Which leads to the next thing...
2. Woodchipper: HOW DO YOU FREAKIN' USE THIS THING?! I gave it fuel, I tried sticking the damn mannequin in there "perfectly" after hearing they're good for resources...I cannot shred them at all. Honestly the mannequins just drive me insane in general, tone them down. lol
3. Better combat: ...I just fought the Abandoned Kerfur not too long ago...yeah I dunno...I feel like combat could use some work, I swear I've been hitting him constantly, but most of my attacks kept missing for some reason. I eventually just stood still and kept the thing against wall and hit him constantly, letting him stab me ten bajillion times. I don't even know how I survived that fight like that and the explosions you take. (I mean, yeah I had it on Easy difficulty, but still. >_>)
Now for my main suggestions...
KERFUR.
1. Better pathfinding: This guy gets stuck constantly, mainly when returning, and it's almost ALWAYS at that bridge. I also had a time where he got stuck in the river for some reason, near the fallen tree, maybe have him stick to the roads or something when returning at least?
2. OMFG STAY STILL DAMMIT!: I know he's on one wheel and is trying to stay standing, but it's just annoying when you're trying to click on him and stuff and he's bouncing all over the place. lol
3. Charging Base: He's a robot, a charging base would just make sense, once he's done with his stuff he can move right to the base and shut itself off instead. (plus the base could keep him from falling down when turned off)
4. Let us name out Kerfurs: ...Because, uh...yeah I dunno. lol
