Homebrew Developer charnold visited the QJ.NET Forums earlier to announce the release of version 1.0.4 of the PSP Dungeons Assault Run 3D Editor.

Aside from a new feature for the editor, the game itself now has a simple AI which should up the challenge in case you thought it was getting a little too easy. Here's a lowdown of the changes (quoting the readme):

• editor changes:
• game geometry view shows enemy's attack animation frame with the bullet's starting position
• game changes:
• simple enemy AI:
• enemies check, if they see the player and alarm other enemies
• enemies are alarmed when the player shoots
• global alarm stops when no enemy sees the player for some time
• enemies evade when the player aims at them
• enemies try to aim at the player, when they are in alarmed state
• enemies shoot at the player (visible bullets)
• collision detection bullets - player, player dies after some hits
  

Further details on running both the homebrew game and its accompanying editor are available in the readmes included with file bundle. You may also want to visit charnold's release thread at the QJ.NET PSP Development Forum in case of any further updates.
