Some good entries here!
Ok, here's my breakdown on each of the entries.
(btw, please don't take offense to anything I say. I'm not criticizing.)
Parsec: Good concept, although currently there isn't much of a challenge. I'd like to see more variety in the AI/ships/weapons.
Simul: A new take on the classics! Adding multiple instances kept the game interesting. Level 2 was as far as I could get
Blur: Classic tunnel game on caffeine. I understand the inspiration for the name.
Mansion Impossible: I have to be honest here. I couldn't figure out how to play this one.
Splut: Other than avoiding the falling blocks, I couldn't figure out the objective. The flag is probably the goal, but without being able to move the blocks, I'm stumped.
Mines4: Classic minesweeper clone. The undo feature is convenient. Allowing the player to hit a mine on the first selection should be changed.
AxePak: 3D pong is definitely my favorite game in the AxePak. I suggest allowing the user to retry by pressing 2nd/Enter instead of only Y/N.
HoMM: The graphics are very nice looking. I'm getting RAM clears when I battle, so I'm not sure on the gameplay.
Advance Wars: There is definitely high potential here. I look forward to seeing this game completed!
WFRNG: Dude, it's so amazing!
What can I say but one word? Epic. This random numbers generator takes random numbers to a whole new level.
Space Dash: Very nice game here. Simple yet entertaining. I think a bit more variety would make this game even better. The custom font looks amazing btw.
Exec: I like what's here so far. I suggest making the jump height a function of the keypress duration. Also, maybe decrease the momentum slightly.
Jump: Very clean and simple. Similar concept to Space Dash. Also entertaining. I suggest making multiple tiers (high/low) to add some variety.
Overall, a very close competition.
