An old rusty key found deep in cave, what kind of door could it open ?
Explore a dense world, fight ferocious enemies and solve puzzles in search for answers.
Master key features :

Item based exploration
Dozens of enemies
Shops, weapons and powerups
Dungeons
Between 5 and 10 hours of content
Lots of secrets
No language support!

The game doesn't hold you by the hand, it's a love letter to hiking and exploration, you have to find your own path and nothing is story-gated.

Master Key's first anniversary!

Hello,

This week marks the first anniversary of Master Key's release. First, I want to thank all the players who played and loved Master Key. Thank you for your reception and support.

If you don't already own the game, now is the best time to get it or gift it, with a 40% discount on all platforms!

Some of you might be wondering what I have been up to this year. And I think it is the best opportunity for an announcement. Check out my most recent project:

Skigill

https://store.steampowered.com/app/3657180/Skigill/
Skigill is a bullet-hell roguelike survivor with a huge skill tree!

The controls are simple; Skigill only uses the directions and a button. Move around and dodge enemies while your character automatically deals with them with the weapons. Then collect the resources left by the enemies to power up and survive.
Game Description Image

The main particularity of Skigill is its skill tree. In Skigill, you power up by investing the resources in nodes of a huge skill tree spanning the entire battleground. This skill tree features stat bonus nodes, perks, and weapon loot nodes. This also means you will have to fight your way or hold your ground through enemies around a node you want.
Game Description Image

I always loved the sphere grid from Final Fantasy X. It is a great concept that allows for flexibility and interesting choices for building our team while bolstering replayability. And I had wanted to experiment with that idea in a game for some time. With Skigill, you will be able to try different builds and strategies on a large skill tree in quick succession of 10 to 15 minute games!

Skigill has a much smaller scope than Master Key and Havenlocked, expect playtests to start very soon!

Havenlocked

I'm still working on Havenlocked, too!
Game Description Image

I am just starting to learn how to work with colors, so you can expect the sprites to look slightly different for release.

Consider following and backing Havenlocked once the Kickstarter campaign is live!

Havenlocked reveal!

Earlier this year I released Master Key, and I really enjoyed my time making it! Thanks to your support and love for the game, but also because I wanted to explore other ideas, I could not resist the urge to work on another game.

Havenlocked takes place on a paradise island, far from civilization and surrounded by ocean as far as the eye can see. Explore the island, its depths, and the sea, all filled with nature, puzzles, and strange monsters. Uncover secrets and escape!

Havenlocked will focus on ideas not explored in Master Key, such as a twin world system, different themes, and a new style of dungeon design. It will also expand and improve upon the exploration, non-linear progression, secrets, and puzzling!

Wishlist it on Steam: https://store.steampowered.com/app/3318450/Havenlocked/ And support it on Kickstarter: https://www.kickstarter.com/projects/778295166/havenlocked

Cloud saves

The cloud saves are now available!

The cloud save system is disabled by default. To enable it, go to the main menu setting and ensure that the button with a cloud and Steam icon is not barred.

The process will turn your saved data into a JSON file that you can find here:
WINDOWS: C:\Users\yourname\AppData\LocalLow\Achromi\Master Key
LINUX: $XDG_CONFIG_HOME//unity3d/Achromi/Master Key
MAC: ~/Library/Application Support/Achromi/Master Key

It will then be downloaded through Steam Cloud and replace your previously saved data once you start the game. The JSON is updated when you load the main menu (including after quitting from a loaded save), or quit using the power button on the right.

However, the cloud save system is still in beta. I recommend backing your saves up in case you encounter a bug.

You can find your saves for Master Key in the regedit under HKEY_CURRENT_USER\Software\Achromi\Master Key
Click export to save it as a file anywhere, you can restore this save by double-clicking the exported REG file.

Please report any problem or successful save transfer.

Difficulty Update

Hello, I received your feedback about the difficulty of Master Key.

The previous difficulty modes were hidden as color palettes, I decided to move them to a dedicated slider alongside the music and SFX sliders.
Game Description Image

Along with this slider come two new difficulties, Very Easy and Very Hard:

Very Easy: double damage, armor, long invincibility frames, boosted health regeneration, full health refill on respawn, and no enemy respawn!
Easy: +1 damage, invincibility frames, boosted health regeneration.
Normal: no modifier.
Hard: more enemies, 1.5x damage taken.
Very Hard: more enemies, 2x damage taken, no health regeneration.

Select Normal if you want a difficulty close to the first Zelda games.
Select Easy for an easier yet challenging experience closer to later Zelda games.
Select Very Easy if you only want to explore and solve puzzles.
Select Hard and Very Hard if you want an unfair and frustrating experience.

Thanks for buying Master Key and have fun!

Master Key is out!

I am very happy to announce that the game is now available on Steam!

You can go play it! But maybe you would like to hear about a few things to enjoy it to the fullest?

[olist]

There is no wrong path. You will make progress wherever you go.

If you can enter a dungeon, you can beat it.

Don't dive into the danger head first. Instead, if it seems too hard, explore to gather more power-ups, and then come back.

That is true for smaller monsters as well, don't hesitate to retreat when one is getting too close. Some are heavy and won't budge.

Don't be afraid to spend money. There's plenty of it to be found to buy food and still buy the rest of the stuff in the shops.

You should try alternate palettes, my favorite is the green one.

It's possible to reduce the size of the window to the one of a GBA, try it!

Complete the main game before the nonograms. That way the nonograms won't spoil you and you will be able to listen to the music tracks you collected in the main game while solving them!

If you liked the game, don't forget to talk about it to your friends or on social media, and leave a review on Steam or Metacritic!

Have fun!
