Ultra Pixel Survive (EP)

You need to survive until day 6. This is my suggestion for playthrough:
Day 1: Go left from the starting position cutting trees, destroying stone and killing enemies if any. Enter the cave when you get there. Go right and farm minerals. Make sure you have enough time to return back to the starting position before night time comes.
Night 1: Build spike floor traps on left and right (2 on each side is good, but you probably only have enough for 2 or 3, so do your best) Kill enemies that come with your sword and the trap.

Day 2: Same as day 1 but go right and off to the right of the screen is beach. There is an achievement for visiting the beach so just go there and come out. Concentrate on farming materials on the right side as much as possible.
Night 2: Build a furnace. We want to try and upgrade the axe, pick, and sword as quickly as possible. Survive same as night 1.

From here, strategy pretty much remains the same. Upgrade sword twice as soon as possible. If you need mineral visit the cave to get just enough. Do not stay in the cave for too long as this is a tough area from day 4 and beyond.

At some point, probably day 4 or so. Upgrade camp fire and build one. Cook whatever meat, corn, etc you have in order to make sure you don't starve to death. Also on night 3, bats start to come. There is a wall and other items you can build that can help you to block the bats but they do get destroyed after a bit so utilize the archer and do your best.

It should not be too hard to get to day 6 using this method and shouldn't take you more than 1 or 2 tries. Good luck!
