Anyway, leviadragon's version also comes with a few unique features that are not present in other builds. The coder gives the following features as well as controls:

* The game is simple.here are 3 type of games:
o Catch the mimigas that fall from the sky
o Ride the Green Tea Dragon
o Escape From the Boss
* They are very intuitive , however these are the controller buttons:
* Button L for change level (at any time)
* Button R for 2 players
o Directional cross for moving 1 player
o Square, circle, triangle, to move 2 player
* Cross for confirm level selection
* It is possible to play with two players with only one PSP
* There is the succession of night and light

Those who want to give Unofficial Cave Story: Return to World should know that there two versions available depending on your Sony handheld. One is for PSP fat while the other is for Slim & Lite. Note that the latter doesn't have support for sound.
