Statement: Additional Account

June 25th, 2014

Dear Steam Community!

We realized, that some of you don´t like the fact, that Ludwig requires an additional account and a login to play the game. We absolutely understand, that this might be annoying, since you already use your steam account to login and play games.

This announcement should explain, why we decided to use an account for Ludwig and why it is still in the steam version of the game.

First of all, Ludwig has been designed to be an educational game which is fun to play at home, but can also be played in school. Actually more than 10.000 students in Austria (where Ludwig comes from) played the game in school together with their physics teachers. The login allows us to provide free class licences to schools and a cloudbased savegame system for the students. So students can play the game at home and continue with their savegame in school and vice versa. This is a nice feature, which is also highly appreciated from all players, which use Ludwig in school.

Ok, so the login makes sense when playing Ludwig in school - but why the hack the login is still required in the steam version of the game? Well, that´s a legitimate question. The answer is kind of unsatisfying for us as well: We´re a small development studio in Austria and we did put really a lot of effort in creating a serious game, which doesn´t suck during gameplay (and so far the player´s reviews for the gameplay are good). We were so excited, when we got greenlight by steam and tried to manage to port the game to steam. Unfortunately, we didn´t have the budget to go as far, as we wanted to go with this port. We would like to remove the login completely and support steam cloudbased savegames instead. We know, that this solution would be much more convenient.

We just wanted to let you know, that we are aware of this problem and try to implement a better solution (no login + steam cloud savegames) as soon as possible.

In the meanwhile we apologize for the inconvinience of having to register for a free account. If you write a review on steam, please consider our will to fix this issue.

Thank you so much for supporting Ludwig and sorry again!

About the Game

Ludwig requires a FREE account which can be created directly in the game or on www.playludiwg.com
This account enables you to store your savegame online. It is not used to track any gameplay data.

2098. Mankind has left the Earth and is now living in space colonies. Ludwig, a research robot from a faraway civilisation and his spaceship are looking for forms of new energy. Unfortunately, mankind´s new space colonies are not listed on his interstellar maps, which results in a fatefull crash with the physis, the biggest station with a billion inhabitants. The crash does not only tear a huge hole into the physis´ protective cover, but also damages Ludwig´s spaceship badly enough for him to lose control of it and crashland on planet Earth. Now it´s a race against time.

Will Ludwig succeed and get his spaceship going in time to save the physis?

  • Explore the area where the spaceship crashed or an enormous dam, travel by balloon through the snow and ice or cross an almost endless desert. There’s so much to discover!
  • Find the weirdest components and construction plans. Use them to develop practical new gadgets to supply Ludwig with energy!
  • Discover physical phenomenons and analyse them in order to reveal the laws of physics and solve the tricky puzzles in the game.
  • thrilling storyline arching over 4 unique environments
  • more than 8 hours of gameplay
  • developed with physics-teachers, pupils and educators - 100% curiculum based
  • comes along with didactic materials for school useage

  • The game tells the story of "Ludwig" - a small research robot who is on an important mission to find new forms of energy for the home planet of the Robotronics. After a long journey he finally reaches earth - just to find it abendoned. Humans exhausted nearly all energy sources and left the planet. They live in big space stations. Unfortunately Ludwig hits one of these spacestations with his spaceship and crashes down on earth. A damaged spaceship, a far away homeplanet in desperate need of energy know-how and 1 billion humans in a damaged spacestation - now it´s up to you as a player to clean up this mess!
  • While following the storyline Ludwig has to learn about the human technologies on earth. Starting with the most basic form of energy production - combustion - he has to advance through a techtree to find and learn about more sophisticated forms of renewable energy.
  • Ludwig doesn´t know anything about the laws of physics on earth (remember - he´s an alien from a far away robot civilization called the Robotronics...). So he uses his scanner to find and analyse physical phenomenons which appear in the gameworld. All the knowledge is stored in a dynamical conceptmap - the knowledgebase.
  • The knowledgebase is empty when you start the game. While playing, it fills step by step with new nodes. You will end up with a huge concept map of physical knowledge on renewable energies. (developed together with physics teachers and educators).
  • The game features 4 unique "themeworlds". These quests in these environments are based on a specific topic (combustion, water power, wind energy, solar energy). The themeworlds are connected by the storyline.
  • Every themeworld features a minigame - called laboratory. A laboratory illustrates the core knowledge of the themeworld (for example: How does a pumped storage power station work? or Where should i place my windmills to get the most efficient energy output?
  • All this educational gameplay is nicely embedded in the storyline. The game is NOT devided into playing- and learning- or assesment elements. You always KEEP PLAYING the game!
  • Ludwig is designed to be fun to play (please judge for yourself ;-) but it can also be played in schools. The game comes along with a set of didactical materials for teachers to support embedding Ludwig in classes.


At the moment, it´s not possible to select the language from within the game. If you want to change the language from english (standard) to another language, please edit the localinfo file in the Ludwig installation directory (C:\Program Files (x86)\Steam\SteamApps\common\LUDWIG):

0 = english
1 = german
2 = simple chinese
4 = portuguese

This game is honestly soo different then anything you will ever play. At first everything is hard the controls are really weird and it's just you talking to your spaceship. After about 30 minutes of walking around you kind of get a feel for the game and everything begins to make since......

The game: You are a robot named Ludwig where you crash land on planet earth, you are a simple robot with a very intelligent spaceship ( that helps you every step of the game). Your goal is to explore and find and discover every element we know......for example we know how to make a fire but Ludwig does not. So you have to go and find parts to make a decoder to read a manual for a BBQ and this allows you to make a fire....but before you get hurt, your spaceship makes a combustion lab which allows you to test all combustibles ( you get to see when they burn, when there is nothing left and the molecules left behind)

The good: The game is its weird kind of fun. If interested in science you get to learn a lot of interesting things about our elements. The world is beautiful, mini games are fun.............a little addicting

The bad: The controls basically suck, The music is repetitive and just sucks ( I had to mute it and play my own music)
a lot of talking between you and your spaceship before you can get going, have to read a lot to fully understand every option in the workshop.

Buy it: If you like science and want a game where you can relax use your intelligence go for it. I know I'll be playing it some more

Finished (almost 100%) in 7 hours. Enjoyable, but I probably won't play it twice, since I didn't see much replay value in it for me. Relatively stable with only one crash to desktop, but I didn't appreciate having to register on their website to start the game, and it would have been nice if the game could be played in a window instead of full screen. Loading screens are longer than I would have liked. Played one level via Steam Streaming on my Mac without trouble.

Game itself was a fun adventure. Graphics were nice and controls were fine. It appeared to be educational, but I certainly didn't learn anything I hadn't already learned in highschool.

Maybe the game is good.
I don´t know that because I am not willing to support account making and always online DRM for a single player adventure game.

Yes, always online DRM, be aware of this before you buy!

Edit 3.7.
After the Announcement that they want to remove the login:
"We just wanted to let you know, that we are aware of this problem and try to implement a better solution (no login + steam cloud savegames) as soon as possible. "
I am looking forward to play the game when this is done. And hopefully I can change my review after I try out the gameplay.

It requires a completely separate account just to play and that isn't stated anywhere on the store page. Why would any single-player game require players to create an account just to play?

I have just bought the game and this is what I have experienced so far:

- The inability to create a new account. It kept complaining that my emails did not match! I know it did because I entered it multiple times. I ended up having to go to the website and after two tries managed to create an account. This was a real hassle and really gave me a bad first impression of this game.
- The sound is sometimes still on when I have turned the game sound and the music right down.
- The sound is very loud in the login screen, there should be an option to turn it down/mute it.
- You have to be online to play this game. You are required to log in before you can start playing. And you are required to create a new account if you do not already have one.
- No option for windowed mode or ability to change resolution.

I will be back to edit this review once I have played the game. So far I am not very pleased with these bad first impressions and I haven't even started the game yet.

This game is pretty good. Here are my thoughts so far:
- It is very easy to learn. The controls are weird but easy to understand and get used to. The tutorial helps a lot.
- The gameplay is fun. The puzzles are interesting and fun.
- The graphics are good, however I wish I could choose the resolution and have the option to play the game in windowed mode.
- Saving the game works fine but there is a bug and it wont save to the server. There is no Steam cloud save option. There is no option to save in the menu. You have to find the save points in the game in order to save, which there are lots of them around. However, in a rush, it might be hard to find one and walk to it in order to save the game.
- The game has frozen once while playing, even though its on medium quality for graphics on a very high performance pc.
- The game is very educational. While most of it is learnt it high school, I managed to learn something from this game. :)
