I've only had this game for 4 days and am already very addicted to it. Loving the free build aspect, would love to share some suggestions with the dev team.
1) Ore location - I've read a bunch of the forum posts, and agree that the only way to reliably find ore is to search cave systems. Problem is there aren't that many close at hand, or so I thought. I discovered the "fly" function, and was stunned to find dozens of worm tunnels underground loaded with small ore deposits. However it would take a lifetime of digging to discover these naturally. Would it be possible to add a new piece of equipment akin to a metal detector - an ore detector? A device that when you're within so many squares of an ore deposit, even if you're above ground and its beneath you, it gives you a signal/sign/light. If the developers don't want to make a directional device (like an ore compass), perhaps one with a simple strength gauge, "you're getting warmer...oops never mind, that was hell"
2) Go west young man - Compass and Flashlight- I watched a bunch of YouTube recordings on the game when I first started, and apparently I got in late, as many of the items that early adopters received basically for free are now embedded in the advanced crafting table - namely the compass and clock. Frankly I think these should be given to the player when they first spawn. Having to find aluminum to make the advanced crafting bench just to have a compass, would have been impossible. Four days and I still haven't found any aluminum. Only recently did I discover that "flashlight" light made it infinitely easier to find ores in caves. I have a color vision issue "red green weak" as do many guys, and the yellow green torch light make finding ores very difficult. I had to become very proficient at recognizing the patterns of ore (the lichen appearance) versus a color differentiation. With a flashlight, wow what a difference. I think a penlight/flashlight should also be part of your starting kit. Building new ones can require the advanced crafting bench, and perhaps it would be more "fair" to give flashlights/torches a life-span, but just an idea.
3) More bears - or bear like creatures. Loving the limited bio-diversity, I hear that biomes are on the way and hopefully with them more creatures, both edible and aggressive. I would like to see more "threats" in the environment, as the survival aspect of the game could be boosted quite easily. Snakes, big cats, etc, to make you build shelter. Wildfires? anyway just an idea. OH, and can you fix the animal clipping issues where bears can crawl out of pits? I tried trapping one in a cage, and it just clips through the walls. Since no crocodiles, wanted to put bears in my moat to discourage visitors =).
4)Reach out and touch someone - Range weapons - swords are great for killing pigs and cows, but you'll just tick off a moose (elk?). I have one that lives just outside my building site, and I got really tired of hearing him bellow. So I tried to kill him... Died twice, and he ended up in my house before I killed him. His replacement spawned even closer. Would be nice to have the ability to build additional weapons. I see that armor will be in the future. How about a bow (or gun!).
5) Melons, melons, everywhere, and not a drop to drink... I understand the watermelon is a good "water" source, but hoping to see actual rivers/creeks/ponds in the future. Building canteens, jugs, etc. to store vs constantly slicing melons (which don't stack in inv). I mean I can carry almost 30 stacks of 64 blocks of stone, but only a couple dozen melons =).
6) If you teach a man to fish... Speaking of water, how about fish? Clams, oysters, seafood, etc. would be a nice addition. Looking forward to the biomes update to see what pops up.
7) Are we there yet? Yep, put me down for a map as well. Right now the other side of the mountain...looks exactly like this side, and when we do get biomes, I'm going to want to travel, and right now the compass is the only thing saving my life (and I had to "gift" myself the aluminum to get that!)
Thanks for the adventure!
Loving the game, just thought I'd share some ideas.
