I recorded some sucky demos in which I die in most maps :/
sm160_negke - really nice, the floor texture reminded me of a Lego base.
sm160_negke2 - yay for low gravity! cool texture theme as well.
sm160_rj - cool finale room, although with the red armor and megahealth I was hoping for more of a fight!
sm160_hrim - nice mouldy castle theme, hard gameplay
sm160_alan - quad + RL always a blast :D
sm160_drew - liked the waterfalls theme
sm160_drew2 - great base theme, I kept running out of ammo though.
These are impressive quality for speedmaps! Sorry I didn't get mapping soon enough to contribute too; hopefully next time.
