One of the most significant and more distinctive features of Serious Editor 2's level editor is that it allows for real-time editing. The level design process for most games often requires the level to be modified in the editor, compiled, saved, and then loaded separately in the game where it can be tested. However, Serious Editor 2 allows for levels to be played and tested within the editor without requiring compilation. While playing the level within the editor, the level designer can directly switch to editing mode, make the desired modifications, and then continue playing, greatly simplifying the final stages of level editing.
