This is my first game for the PSP (actually, it's my first game written in C/++ for anything , although I know Java so the syntax is familiar.)
This game tests your ability to quickly react to changes on screen. On screen, you will see the X, circle, square and triangle buttons, along with a green/red bar along the top of the screen. When one of the buttons turns red, quickly press that button. If you press it quick enough, the green section of the bar will increase, but if you take too long then it will decrease. Pressing a button while it is white also decreases the bar. You simply have to stop the green bar from running out for as long as possible. Later on in the game, the directional buttons and shoulder buttons will also appear to make the game a bit harder. (paragraph taken from the readme file)
Start pauses the game, Screen button saves a screenshot to /PSP/PHOTO/RGScreen.bmp, Home quits.
(I know it has a rubbish name, but it's a suitable name because the game's rubbish too :) )
