I really like the new tree planting system as the game didn't seem like a proper mining game without it. The first thing I did when I started my game was plant trees. They grow back rather quickly which allows for easy farming. You can also burn wood into Coal which seems to work pretty well. It...

I notice you aren't using your L/R spots on the hotbar. I didn't early on but that's something really convenient to get used to. Say your default is sword in L and shield in R. Whenever you hit 3 for your pickaxe it will just switch to that, and hitting 3 again will cancel it and go back to what's in your L/R. If you hit 4, though, since the flashlight only needs one hand, you'd use that in L and your shield in R. And you can hit ~ at any time to cancel out of any other active items and switch to L/R.
The downside is that while we were playing with the Terraria holiday stuff, I was so used to that it was hard to get out of the habit. I also tried using E to open doors and such quite a bit.
Wow, those trees can be packed close together can't they? That'll make farming wood easier.
Using the L/R slots is really useful. I like to keep a weapon in there so I can switch to it quickly whenever I'm in trouble.
Last character wipe soon? Oh man, the only thing keeping me from playing this obsessively is knowing that my progress would get wiped with the next update. Soon I'll be racking up the playtime!
WELL, it seems that a universe and planet wipe may happen. From past wipes it seems that might also mean your ship too.
Yeah that was a bummer. Oh hey my character is still there! Ship is empty. I'm parked at a planet that's really too difficult for my level, ship has no fuel. Never set a home planet. Might as well reroll!
And don't forget 'x' that swaps between your current tool and L/R and back again... I run around a lot with the pickaxe/drill and hit x when enemies show up to whack 'em down, then x again to keep digging....
That looks like Terraria, which makes me interested in learning more about the game. =)
It's very similar to Terraria but in space and still in development.
