Macintosh and Linux users, we are aware of a crash bug in multiplayer. Both OSX and Linux may crash as a client when the host disconnects from a multiplayer game. OSX may crash when attempting to connect to a nonexistant host. We are working on this issue. Our apologies for the inconvenience.

Changes in 1.1.5:

    General Updates
  • Added a tutorial for Booster and Logic. Step by step tips will guide you from basic through advanced gameplay.
  • Added gamepad support. Now you can play Booster Logic with a gamepad, without resorting to external software.
  • Added a new pack for both Booster and Logic, SB_Bonus3. This pack's difficulty falls around the middle levels of the Standard packs.
  • Added more general controls to key bindings.
  • Updated art, including floor and wall tiles, across both games.
  • Tweaked various older Booster and Logic levels.
  • Added a confirmation menu on game exit.
  • Integrated with the SDL and SDL_net libraries for networking and joystick support.

  • Booster Updates
  • Booster now has save points! Activate a save, and when you die you will be able to resume from that location. Only one save can be active on a single level at a time.
  • Saves in multiplayer function as respawn points. Activate one, and if you die you will be able to come back from that location, without resetting the level.
  • Added save points to many Booster multiscreen levels (Standard 301 and above).
  • Improved Multiplayer support and added many server configuration options. Create your own modes, from speed Booster to forced 100% collection!

Changes in 1.1.4:

    Booster Updates
  • Updated map324 to make it work with a Launch Pad change.

  • Logic Updates
  • Added "normal" difficulty and bumped the current maps up to "hard" difficulty. The normal maps are more straightforward and may give hints on how to complete their hard counterparts.
  • Slightly tweaked most maps to adjust them to normal or hard, and further modified each map for the alternate difficulty.
  • Shuffled the order of a few of the maps to account for the new difficulty setting.
  • Updated the Hunter AI. They shouldn't be quite so easy to confuse now.
  • Clicking on an item will now use it, as an alternative to the "use item" key.

  • Editor Updates
  • Added a "Bundler" tab to the editor. The Bundler is used to create Level Packs, and gives more information than what we had before.
  • Added a "Resize" editing tool. It's a visual representation of the map size. It shows exactly where the extra tiles will be added, and what parts of the map will be cropped off.

  • General Updates
  • Booster Logic now supports profiles. Go to Options->Profiles to create a new profile. You can then select your profile from any map selection screen. Profiles store separate scores and level unlock data, along with configuration options.
  • The menus have a new look.
  • In-game buttons are now all a standard size.

Changes in 1.1.3:

  • Improved pellet locations in many Booster maps.

  • Added quicksaving and quickloading to Logic. F5 saves, F8 loads, and the keyboard numbers select a slot. The saves are persistent across restarts.
