Sqrzx 3 by Retroguru is a pretty insane Jump'n Run Game with Puzzle elements available for a total of 17 systems (including AROS).
Also check Sqrzx 1 and 2 also available from the game website.
Do bear in mind that this is an old playability difficulty setting (it's hard!).
Sqrxz 3 is now available for AROS and Amiga OS4. Sqrxz and his girlfriend were on a romantic adventure journey in a jungle somewhere here on our planet. All of a sudden Yve gets kidnapped by an evil power and Sqrxz is forced to collect dozens of shiny little rings to free her. The old ruins he has to explore are anything else than safe. Traps are spread all over the place, and Sqrxz is not alone!
