Updates on the development of coding puzzler Robo Instructus

Robo Instructus: 3 Years Old

I'm a game developer. I made robot engineering puzzle game Robo Instructus. For my previous posts look here.

Robo Instructus came out 3 years ago today. Let’s take a look at the last 12 months.

To celebrate 3 years Robo Instructus is 50% off on Steam & for the next 7 days.

The game has received a few updates over the year, the latest 1.34. Notable improvements include full game translations in Español (es) & 简体中文 (zh-CN) these were contributed by generous multilingual heroes to the OSS translation repo just under a year ago. I also added autocomplete configuration allowing completion using the return key & improved the scroll bar usability in September.

Sales by platform   In the last year
Steam 3984 618 39 5

The vast majority of sales continue to be on Steam. Down from 822 last year which is to be expected as the game ages.

Last year Steam sales by region  
United States 28%
Russian Federation 19%
Germany 7%
Brazil 4%
United Kingdom 4%
China 3%
Canada 3%
Sweden 2%
Ukraine 2%
France 2%
Other 26%

Last year Steam sales by OS  
Windows* 86.2%
Linux 7.9%
Mac 5.9%

* Steam doesn’t actually count Windows explicitly, so this tally is the sales that are not counted as Linux or Mac.


On Steam the game is currently rated Very Positive with 80% of 50 user reviews, nice to see the “very” qualifier there now! I guess having at least 50 reviews is a requisite.


Looking at a couple of choice Steam achievements, The Gist which you get for completing the 4th level (ie you’ve actually had a go at the game) is 65%, up again from 63.6 last year. Open The Vault which you get for completing the game is at 0.7%, down from 0.8. So I guess a few more people have played the game this year, but struggle to complete the whole thing.

You can play the Robo Instructus demo and buy the game on Steam &
