Aro is a duology of games released in 1996, & 1998. The first game was a remake of Zipman 3. Both are platformers starring the titular bird as he/she goes through multiple levels grabbing circles, & power ups. Only the shareware versions have been found so far, with the full versions yet to circulate anywhere. Aro 2 might be an unreleased game that never got finished due to poor sales of the 1st game.
