What the developers have to say:

Why Early Access?

“Hex-a-Decimal's core gameplay has been finalised for a while now and I feel comfortable charging for a more complete experience than the demo has to offer. I have the first 60 levels fully implemented and as I build the latter half of the game and expand its mechanics I would like players to be able to give feedback on parts of the game that are beyond what the current demo can provide.”

Approximately how long will this game be in Early Access?

“Less than a year, with the full release happening (at latest) in early November 2027”

How is the full version planned to differ from the Early Access version?

“The game will have about double the content. The demo has 3 components and 30 levels, the current paid version has 6 components and 60 levels, and the finalised version will have 12 components and over 150 levels. There will also be expanded editor features such as the ability to make levels larger than one screen, and the ability to make entire sets of levels (essentially a "world" editor on top of the already existing level editor).
There will also be plenty of visual polish, better menus, more options, and the game will overall be a more complete and polished experience.”

What is the current state of the Early Access version?

“The current early access version has 6 components and 60 levels, as well as the level editor which was used to make the levels that are already in the game and can be used to make countless more.”

Will the game be priced differently during and after Early Access?

“The price will most likely stay the same, but discounts from sales will be larger during early access and participation in sales might decrease or stop entirely once the full game is out.”

How are you planning on involving the Community in your development process?

“I have been posting the occasional devlog on my YouTube channel MCHS Productions and have a Discord server where I post updates regarding the game's development. Community updates and interactions will get more frequent now that the game is being sold, since I want everyone to be up-to-date with the game's development, especially those who have spent money on my game.”

About This Game

Hex-a-Decimal is an automation puzzle game on a hexagon grid. Set up lines of conveyors, pausers, sensors, and various other components to get signals to where they need to go. It's a challenging game that anyone can pick up, but the question is: how far will YOUR puzzle solving skills take you?

Master the game's many puzzles and mechanics:

Hex-a-Decimal is a game full of challenging puzzles and complex emergent systems. As the levels progress, you'll learn to think in a whole new way as the game introduces and expands on easy to learn / hard to master mechanics.

Optimise your solutions:

Whether you're stuck on a later puzzle or have simply completed them all, levels in Hex-a-Decimal have lots of replayability. With three individual stats and a total score, you can go back to a level you completed and spend hours trying to optimise your solution.

Unleash your creativity through the built-in level editor:

Got an idea for a challenging new level? Make it yourself! Hex-a-Decimal comes with its own level editor, the same one which was used to make every level seen in the game, and countless more can be created using it.
