I'd never played Abadox before actually, but from what I played yesterday it was kind of brutally hard lol. Managed to beat the first level though and get to the downward scrolling one, but then I gave up because I had to see if the other games worked too. A big reason I bought it was because the music is made by Kiyohiro Sada, the guy behind the music in Contra and Bayou Billy. And of course the gameplay looked good as well so I thought it was a game I should have. 
But it definitely is one of those games you need to learn the levels of to be able to beat. I'll give it another, longer try later today.
