I noticed that there is no achievement guide for this game although there are a lot of hidden items required for the achievements. This game is easy if you know what to do. However, the "tutorial" doesn't really help much so i'll help in giving some pointers for the game.

I'll also help with giving a trick for killing the bosses.

Before you begin the game, you might want to read these first.
- You need 1 MP to rest in a bed. In some area (especially layer 1), there will be a glowing light which will fully recover your HP and MP. In order to use it efficiently, spend all your MP in the bed and after you run out of MP and need to recover HP, use the glowing light.
- Cure will recover less HP than resting in bed. However, you might want to use Cure on deeper layers because it took a long time to backtrack and recover HP.
- You can dash by holding shift.
- Save a lot in a separate save. The game can randomly crash (it has been reported as known bugs here) and i know you don't want to start over just because of that.
- Save a lot. If you get poisoned, load your save file so you can sell all "abnormal states" (special status) items.
- Examine all walls in every sides, especially on the first few layers. Who knows what you might obtain from that.
- Don't use the keys on every door you find. Try to efficiently use the key by not unlocking the door that you don't really need. If there are more than one different door blocking the area and you only need to unlock one of them, choose the door with the priority as follows: copper, iron, silver, golden.
- Get all secret items in the area before facing the boss except for layer 3 (if there is any).
- It is recommended to get Dark wave and Cure skill from Special skill scrolls and Divine blink from Natural Reel first. The first two are required to progress easily in the game while the last is required for an achievement. Once you get the scroll, you can save and load whenever you get the skill that you don't want.
- Spend all of your money (and sell all items that you don't use) to buy Power Medal and use the medal and other permanent stat enhancing items that you get.
- You can assign offense magic in the quick slot by pressing T or G.
- On deeper layers, you'll find "???" item. This item will recover a little of your HP and MP plus permanently raising 5 attack.
- Although you can make some money with "Golden Touch", you can finish the game without that easily.
- At some point, you'll get God's key. There is no special door which can be unlocked with this key so you can use it whenever needed. You still can finish the game without using it.

The boss has a high HP so you might want to cast Dark wave in order to avoid taking too much damage. Dark wave can be obtained from Special skill scrolls. If you don't have the skill, you can still kill it easily as long as you have Cure or items to heal yourself in the middle of the fight.

Defeat the Boss

This boss has a tremendous amount of HP. As usual, use Dark wave to blind it in order to avoid taking too much damage. I even use the skill twice in order to kill it.

If you still don't have the skill yet, you better skip this boss and do it after you have better stat. You'll need a high attack stat in order to not strain your hands when you are killing this boss, but again, i didn't use the secret weapon in this layer to beat it so it might be better to use it first if you still want to try to kill it.


There is a portal in the southwest area of the map which can teleport you back to layer 9. You can activate the portal by pressing Z. There is also a merchant to the north of the portal.
