A Walk Through The Snow: Uhh... nothing obvious springs to mind? It's completed, quite polished and has no scripting errors that I found. The secondary path is somewhat redundant, but there's nothing wrong with it being there as such. (This would mean a full 30 points.)
Alosona.4: Both unfinished and very short, -2. Rushed ending, -2. It's possible to bypass the event on the second map and fall offscreen, -1. Non-trivial text visibility issues, -1. -6 preliminary total.
DELETE: Unfinished, -1. Rushed dialogue in a number of places, -1. Possible to gain infinite ammo from the event that gives the shooty gun, for what difference even that makes given that it recharges so quickly. Maybe a small scripting error somewhere on the big map before the end? -2 preliminary total.
Don't Let Go: Everything is servicably functional toward the mod's end, although I imagine it would get very silly if it were attempted to be played any other way. I will say that I was pushing it close on time, leaving little time to clean up the mapping, along with a couple of minor errors I can still notice. For that I'll dock at least 1 point overall.
Hullet Bell: Using the secret level skip too near to the end of a stage will fail to skip the fight but spawn no boss, -1. It's also seemingly possible to infinitely milk the final boss for powerup 'score' but even professional game designers still struggle with that one
-1 preliminary total.
Pawprint Paradise: Again, everything seems to work properly here, unless someone found a mis-cued interaction somewhere.
Story: From what I remember: Mahin has a normal facepic/dialogue at some point when he's not supposed to, -1. Music continuing to play after the Balrog battle, -1. Possible to get outside the map in the final level (according to Hiino), -1? Also not finished and (albeit intentionally) has a sizable portion of the unedited game included, -1. -4 preliminary total.
Terri's Night Out: The 'door' outside uses KEY for its event instead of PRI while there are still enemies moving around, -1. A couple of events could have been scripted a little better but aren't technically mistakes. -1 preliminary total. Use of borrowed material may be a point of contention?
