I have all of LJ's games. My thoughts:
Cubixx: Its an awesome game, Love Qix games and this is a very impressive one. Very much hurt from the lack of options, it so badly needed different rounds to make it one of the best. But its still great so 7/10
Steller attack: hated this game at first, controls were awful, yet the more I played it the more I loved it, still cant control it with one of the options, but now I'm loving the game, its the minis game ive changed my mind about the most, good options too, very enjoyable. 8/10
Vibes: Had difficulty with this game at first too but got used to it very quickly, again very good game, nice to have a game like this which has handmade patterns rather than computer ones of very dull directions. Did have trouble with one or more of the tracks, bought it up at the time but I found I couldnt record it when you asked (by which I mean it still happens, but my camera blurrs the whole things and I find it hard to set up infront of the camera while playing!!) Probably a 9/10 but the bug drops it to 7/10
Ace Armstrong: Found it impossible at the start (a theme with your games) and even now its a very big challenge, although watching some of the walkthroughs helped (such as the 1st boss, i didnt use the special weapon until I saw you do it, which took forever to kill the boss without). Still only made it to level 3, but its a good game, very challenging. 7/10
and thats my (Seemingly very long) view!
