hi, zigi.
my 2 cents:
i wouldn't want to dial it in as tight as you describe where the criteria, instead, is within
the first post with emphasis on
Overall Player Experience which encompasses every aspect of a game.
beyond that, you'll have to trust that i can appreciate all themes, styles and play that fit into the TD subgenre.
and my "taste" is "anything that works". i can appreciate it all.
does pixel art belong in a 3d game? sometimes, absolutely.
vector art in an underground setting? the same.
5k poly rhinos in a marshmallow factory? you get the idea
if it works together, i'm into it.
finally, for the record, i can envision "1 level with 1 enemy type and 1 turret type" as an amazing game if enough Overall Player Experience is applied.
and, so can you.
