The FreeBASIC version of a notorious QBasic mini-game that was originally created for a "one key" game competition where the goal was to create a game controlled with one key.
Red Jumpy Ball features a brilliant concept in which you control a red ball with one key inside levels featuring many platforms. The ball always moves toward east and you control it by holding the action key which determines the height of the jump. You can also break walls by holding the action key for a longer period of time when blocked. The gameplay includes many bonus items to pick up and very well thought-out and motivating scoring.
This version includes many game modes, all accompanied with challenging high scores to beat, but it still lacks a lot of polish, from better graphics to missing sound and music.
