Shooting yourself in the foot with marketing and branding on day one is a "made by engineers" tale as old as time.
VVVVVV (6 V's) is a fun game (I've played it before, and it has "overwhelmingly positive" reviews on steam). VVVVV (5 V's) appears to also be a game on Steam with mixed reviews, maybe looking for customers confusing it with the other game?
No surprise that VVVVV gets worse ratings, it has 1/6 less of what makes the game fun
