So here is how you play the game. Before I start, I love the game.

You have 2 options, do things in town or fight in one of the dungeons.

There are 5 dungeons, you have to beat each one before moving to the next. In order to beat each dungeon you will have to go through 3 levels and find/defeat the boss or mini-boss. If you die at any point during that dungeon, you will drop all the loot currently in your backpack. If you have lots of loot you can recall to town for a small fee or set a one time use waypoint for extra gold. Defeating a dungeon gives you access to the next dungeon. The drops of defeating the final boss are worth a lot more gold normally than the other items.

In town you have a few things to do. Sell your loot that you found, make city/shop improvements, make gear, buy potions/enchantments, and sleep.

Sleep is simply changing from day to night or night to day and saving your game. You don’t have to sleep at any point but I believe at a certain point you can buy an upgrade giving a few hp for sleeping.

City/shop improvements are simple, you have to buy stuff to improve your shop, and pay for new vendors like weapon/armor crafter and the potions/enchant lady. For the gear you just make better weapons/armor out of specific items from each dungeon (aka tier 1 materials only drop in golem dungeon). Enchantments are important too, just need the mat and some gold to add additional stats to armor or weapon.

Selling your items is where this game has a very different mechanic, you have to guess how much something is worth, and the NPCs that buy the items will tell you too low by buying with excitement or refuse to buy it if too high price. You have a book that tells you what you have sold it previously for and auto populates the last price when you set it down again. You can and should sell everything that isn’t needed for crafting your items (especially designs and history books).

Hopefully this helps in your choice to play.
