Blocks 3  
Excellent concept and gameplay, cool art, really high production values for less than two megs. The level editing feature is a nice touch, too.

Fenix Blade  
You mean this is the unfinished version? Wow. If only there were a Windows build and the in-game songs were MOD or XM (for those of us who still have crappy FM-based midi playback)...

Frenetic  
Very classy, and insanely polished for less than a month. Gameplay is simple and instantly familiar, but fun and with some original aspects added to it. The graphics good, with lots of transparency and nicely done textures.

XOP  
Excellent gameplay, good weapon selection, nice unlockables, very Treasure-esque. My nitpicks are that the graphics are a bit TOO retro, and don't do enough to distinguish stuff that's in the player's plane from stuff that's outside of it, and I can crash it often by choosing weapon 2, then 6.

Magic Maze  
Great idea, good gameplay! I thought the player sprites could have used more detail and maybe should be drawn such that they didn't appear to lie in the same plane as the map, and I would have liked more than one chiptune as BGM, but these are minor.

VoID  
Nice graphics, and very high quality sounds, but it's sloooooow (hovers right around 8 frames/sec on my 1200), hampered by the lack of a full-screen mode and 19MB seems a bit large for what this game is (an enhanced Missile Command, basically). Good start, though.
