As others have said: It’s extremely glitchy, the controls are cumbersome a lot of times, and I ended up flying through walls more often than skating on them.

The premise of the game is really intriguing, and I would like to see this game in a more complete state, but as of right now it is virtually unplayable, unless you enjoy breaking games.

An example of glitches, besides flying through walls: You can die in the pause menu, you can manipulate your dead character in the pause menu, you can die while still paused after dying while manipulating your character in the pause menu. You can fly through floors that are solid on the top surface but not on the bottom surface.

DeadOS is less a game and more a really entertaining toy where you generate a city, populate it with people, and watch a zombie outbreak of your creation slowly take it over. There’s no win/loss state, and your only task is to keenly observe as zombies convert the living, civilians run in droves from the impending horde of undead, and cops create blockades around infection zones to slow the spread.

Though the graphics and presentation are simple, the scale of the simulation impressed me; up to ten thousand people can be simulated in the city. It’s oddly satisfying to watch a fleeing crowd of hundreds, abstracted as a bunch of scurrying yellow dots seen from a bird’s-eye view.

There’s no other game on PC like this. It’s already a pretty nice little sandbox game as it is now, can’t wait for all the features that come out for it over time. I completely recommend this game.

~really nice games, good graphics, great sound effects, absolutely horrible music. Does anyone know of any way to turn the awful ‘music’ off ? ..and it would be great if the added more puzzles -or the ability to import some maybe, or a DLC pack ..?

Block Machine

Block Machine

Block Machine is a difficult yet poorly explained programming puzzle that combines the joy of doing homework for computer science class with the eerie satisfaction of toying around with Redstone in Minecraft.

In Block Machine, you build machines from blocks (who would have guessed!) to solve a variety of programming tasks. Block Machine’s programming model is unique: Blocks are both code and data, and all computation happens in parallel. Von Neumann would have loved this.

15+ Different Block Types to Explore

How many different ways can you find to use the basic arrow blocks? Or maybe you fancy the charged battery blocks? Wrap your head around the different capabilities and use them to build the smallest and fastest Block Machine.

25+ Challenging levels, ranging from HARD to REALLY HARD

Solve difficult programming puzzles in this Turing tarpit. Can you beat the global highscore in any of the three categories?

A Sandbox mode to mess around to your heart’s content

Build that 1000 block machine your dreamt about last night. Or don’t. It’s a sandbox!

Very cool simulation. I have mainly been using it in Video mode with ripped VHS tapes to get some cool visuals for streaming / video synthesis stuff. Dev also responded in forums and added requested features, which is always a big plus.

Save Data

Save Data


You are a data-integrity program inside of a computer and your job is to prevent other programs from having their data corrupted!

“Enemy” programs emit electron projectiles and your job is to deflect them to “ground” and not accidentally damage the programs themselves in the process. Features 3 worlds of crazy bullet-heck action with semi-randomized room order and an upgrade system that provides a bevy of interesting ways to progress!

The story behind Save Data

Save Data is part of what has retroactively been termed a “molasses jam” run by the Bay Area Dev Collective. The theme of the jam was to make a violent genre non-violent. As I’ve had a growing interest in action games, specifically of the shoot-em-up variety, naturally I wondered what it would be like to make such a game non-violent. The result is shoot-em-up where you have to protect the “enemies”!

The other molasses game jam games are also on steam:
