Pulse is now available on Android under the name Micron



After months of work on the port, which involved rebuilding the entire game in Unity, touching up all the existing levels, music, and sounds, testing and optimizing, creating new levels and music, then some more testing and optimizing, Pulse is now available for Android in the Google Play store as Micron!

Micron is also coming to iOS very soon, and maybe some other platforms too?

Porting Pulse to mobile devices

I’ve been working on porting Pulse to mobile devices (Android and iOS).  The game was written in Flash, which means it could be deployed to both Android and iOS as an Adobe AIR  application.  The controls and UI would need some tweaking but otherwise the game would work as it is.  Or so I thought…  I deployed Pulse to a Samsung Captivate and found that the frame rate is very poor.  I isolated the issue to the use of vector graphics, and the typical optimizations didn’t have any significant impact.  Essentially, all the graphics in the game need to be redone with sprites.

I found a couple of cool sprite frameworks for Flash: ND2D and Starling.  Starling is especially promising and I spent some time testing it.  Then I realized — after several hours trying to figure out why my app wouldn’t run on my phone — that Stage3D, the new API that both Starling and ND2D are built on, is not available on mobile devices yet.  On top of that, the effort required to update Pulse to use sprites was starting to look substantial (especially considering how simple the game is).

So, of course, I decided to port the game to Unity instead.  My plan was to look at Unity after I finished Pulse anyway so I figure the experience won’t be a waste, and Unity will let me target more platforms than Flash.

Unity is designed for building 3D games so the first thing I have to learn is how to use it for a 2D game.  I’m finding this tutorial to be very helpful.

I also need to figure out how to handle audio syncronization and latency (by far the greatest challenges of making the original Pulse in Flash).  In Flash I had used the excellent StandingWave 3 library.  There doesn’t seem to be anything like it for Unity.  Luckily, Unity seems to be much better at both syncronization and latency out of the box.  When you play multiple sounds simultaneously Unity will actually play them in sync (unlike Flash) and you can choose to prioritize latency over performance, which is nice.

I’m currently working on porting the game logic over from Flash.

Early versions of Pulse

Pulse went through various changes during development. Here’s a look at some of the early versions of the game and the changes made at each stage.

Initial Concept

In the first version of Pulse the grid looked like a wooden board game and the projectiles like tiny sunbursts. You can see a reflector on the right side but it didn’t do anything yet. At this point I was more concerned with getting the projectiles firing in time to the beat.


The game board was given a more abstract look. The reflectors could be dragged and dropped on the board and the projectiles reflected as they should. The “toolkit” was placed on the right side along with a start button where the pause button should be.

Another Redesign

The sidebar was moved to the left side and a background effect was added. Here you can see the early title of the game: Supersonic. It didn’t become Pulse until the very end.

Near Final

The game board was redone again for a cleaner look, the sunbursts were replaced with simpler orbs, and the sidebar was cleaned up a bit as well.

Final Version

And here’s the final version.

Create music as you solve puzzles in a series of unique soundscapes. Pulse is a fusion of puzzle and rhythm gameplay inspired by games like Rez and Lumines.

The game was created for Kongregate’s Project Eden contest, in which it won 2nd place.
