I beat both Snowfall's 'new' levels yesterday like three times (trying to find every secret, undertaking in which, BTW, failed dramatically) and I have to say that, even if I enjoyed them both, I liked 'Pipe Dream' far more than 'Neutrino'.
'Neutrino' has, like 'Zeta Base', a freely and careless usage of textures and sprites that feel out of place, specially in the rooms, whereas in 'Pipe Dream' the only thing I found out of place was the map of 'invurban.map' at the beginning of the level.
What's more: what about those void research projects? I expect them to not affect negatively future research projects. Or what about those empty cases? Not even an amulet?
BTW, the placement of the M60 inside a chest in 'Neutrino' broke my game twice. You see, it occupies two slots of the chest and if you try to pick it up by clicking the left slot, the game crashes (the right one draws the weapon out of the chest).
Like most of you, I got a blank screen at the end of 'Pipe Dream'. Too bad.
Anyway, leaving aside the 'criticism', both levels are enjoyable, well designed and exploit a lot of features from the TC. Snowfall sure has talent for mapping. He just needs to be aware that adding stuff that identities other levels (like the gong from the Asia missions) into his own doesn't always fit.
