planetblupi - a delirious spell-binding game


planetblupi [optional...]


Planet Blupi is a strategy and adventure game. It subtly blends action with thought-provoking challenges. Behind the quiet and gentle facade, you´ll enjoy a fascinating diversion full of surprises. Planet Blupi is ideal for ages 12 to 99..

This version contains over 30 missions and a built in editor, which enables you to construct your own missions.


Planet Blupi supports at least GNU/Linux 2.6.32, macOS 10.9 and Microsoft Windows Vista. If your OS is not listed, maybe it´s possible to build yourself the game. Most Unix and Unix-like OS should be supported.

For the video output, a 3D accelerated video card is highly recommended. It´s still possible to use pure software rendering in all other cases.

For the sound card, any cards supported by ALSA, PulseAudio, macOS or DirectSound should work fine.


The game Planet Blupi runs in full screen by using your desktop resolution. If you are encounting errors, you can start the game by default in windowed mode. Proceed as follows:

Quit the game Planet Blupi.
Open the file share/planetblupi/data/config.json with a text editor.
Replace fullscreen: true by fullscreen: false.
Save and restart the game.

In this mode the screen is no more scrolled if the mouse touches the window borders. Use the keyboard arrows instead.

It´s possible to start the game with --fullscreen off instead of editing the config.json file.

Another way is to start the game in legacy mode. With this mode, the game runs with the original 640x480 resolution. Use --legacy on the command line.

If the problem persists, maybe you should try to start the game with the software renderer. Edit the config.json file and add "renderer": "software" or start the game with --renderer software.

Another possibility exists. You can try to change the driver used by the accelerated renderer. By default it uses "direct3d", you can change by "opengl" with "driver": "opengl" with the config.json file or --driver opengl by command line argument.


The left button is always used in three steps:

Select a Blupi.
Click where you want him to act.
Click the button corresponding to the required operation.

If the chosen Blupi is already selected (blue or red circle around him), step 1) is not necessary.

You may select several Blupis by maintaining the Shift button pressed.

The right button is a shortcut. It orders the selected Blupi to do the most useful operation on the selected spot.


Scrolls the visible part of the scene.
Shows or hides items.
Describes the goal without interrupting the game.
Normal speed (x1).
Double speed (x2).
Returns to place of mission departure
Bookmarks a spot.
Returns to the corresponding bookmarked spot.
Temporarily suspends the game (excepted with the hard difficulty).

When you switch to another application, the game is automatically paused.


The music is provided in OGG and MIDI formats. The OGG variant is preferred because the render is the same for all platforms. For purist fanboys, it´s possible to enforce the MIDI variant by starting the game with the --restore-midi command line argument. Note that in this case, it´s possible to lose some instruments, it depends of your system.

You can edit the share/planetblupi/data/config.json file and add an entry "restoremidi": true, or simply use the new settings available in the global settings screen in the game.

If you want, you can overload all musics with yours by providing OGG or MIDI music files in your user directory.

On Windows, type %APPDATA%\Epsitec SA\Planet Blupi in the file browser. On macOS, look at ~/Library/Application Support/Epsitec SA/Planet Blupi. On Linux, look at ~/.local/share/Epsitec SA/Planet Blupi.

You can create a music sub-directory with your musics. For example: %LOCALAPPDATA%\Epsitec SA\Planet Blupi\music\music000.ogg.

Only 10 musics are supported: music000 to music009.


Print this help message and exit.
Print version and exit.
Change the speed rate [1;2] (default: 1).
Set the timer interval (refresh). The default value is 50ms. This is an advanced option because it changes the main events loop frequency.
Load in fullscreen [on;off] (default: on).
Change the window scale (only if fullscreen is off) [1;2] (default: 1).
Start the game in legacy display mode (640x480).
Set a renderer [auto;software;accelerated] (default: auto). Use the software renderer if the accelerated renderer is bugged. Note that you can try other drivers (option -d) before forcing the software renderer.
Set a driver [auto;direct3d;direct3d11;opengl;opengles2;opengles] (default: auto, ignored with software renderer).
Enable the recorder feature (F3/F4). When playing, you can start a record with F3 and stop with F4.
Play a record generated by F3 (--enable-recorder).
Restore funny original bugs of older versions < v1.9. It can be very fun and interesting for speedruns.
Tower rays: with this bug, it´s possible to add rays on a map even without tower. It´s possible only when building a new map.
Mine flag: you can build a mine without prospecting if you know exactly where is the flag case.
Enemy control: you can take the enemy control by going in an enemy factory while the door is open.
Duplicate everything: this bug is very useful for duplicating objects by sending the same order to two Blupis.
Take trapped ennemy: it´s possible to take a trapped enemy; it´s useless but possible.
Set fire: you can add invisible fire on every type of cells (when building a map).
Restore playback based on MIDI music instead of OGG.
Enable anti-aliasing [on;off] (default: on, ignored if windowed).
