Right now, I will seperate the games which I remember into groups, and comment on them.
Space Barrage: Nice polish and gameplay, but pretty hard to get past wave 1.
Dark Rider: incredibly addicting, but unfortunately I lost my copy.
Offender: Very good game, but needs bosses and only 30 or so levels. It got kinda hard after mines came in.
VectorSchlaut: Very good game, but gets really hard on the last level. It needs more levels, BTW.
Shoot Things: ok game, nice powerups, but didn't meet the spirit of the contest. It wasn't vectorized at all.
SV Racer: stupid, annoying game.
iDevil: has some potential, but as of now it is boring. Cannot die, boss = too easy.
Past Blasters: It was a good game, but I just don't like it. Didn't hit my chord.
Jellybean Fugue: great potenital, but just too easy. Got boring after about five minutes. Great maze gene3rator, BTW. I cannot copy it in any way.
Dokutsu: What's the game?
Nerak Attack: I do not have enough access privileges to install Open AL
Infilitrator: could not download.
I know there's more games, I just forgot them.
I will edit this post when I find out all of them. If you know any more, PM me, and I will add them.
