The game is actually quite hard for me. Also playing on A600 with fastram there are some slowdowns. Bet it would play nicer on 020. GFX are nice, especially the ball itself and titlescreen. Right now there are 8 levels, but the author says there will be more if there is interest.
Keep an eye on the Retro Game Compo page, two games (Robbo AGA and Bomber) are still in development, but they should be released any day now !
