Seconded!
This looks awesome, as usual, but sadly I'll have to again pass. I don't have $600. =(
Make a frikkin' PC version, even, Sony. Your fans await such a thing. Sure, the DS might not be possible, but PC is entirely plausible and might even boost sales of the Lemmings titles.
EDIT: Doom 3? Lemmings? Whaaaaaaat? That sounds awesome; I need infos!
