BGP Level Builder: Mars Lander Edition

  • Integrated Builder / Runner: Build and test your levels all within one unified interface! The BGP Level Builder features an interface which you can use to build and play your level. There is no need for loading or compiling, you can easily switch between modes on the fly.
  • Auto-tiling: Programming magic makes terrain placement lightning fast! Click and move the mouse and watch as the terrain automatically aligns to create a seamless looking level. You can, of course, still manually place tiles if you are so inclined.
  • Level Codes: Share your levels with others using a simple text code! All the levels you make with the BGP Level Builder are saved as plain text strings which you can share with ease. The codes can be posted on any social media site.

  • Implied game-modes: The game objective changes to fit however you make it! Don't place an objective and the game will automatically switch to a Collection game-type where you must collect all the point-scoring objects to win.
