I'll let you in on a secret, I really want to like HeliCab Express. When I saw it on the store, its colorful pixel art and (clearly) Choplifter-inspired gameplay had me squeal with excitement.
Then I played it.
The basics are there; you guide your helicopter's forward and vertical motion to collect people from skyscrapers' roof tops - plus it looks great. But actually controlling the game is like playing Flappy Bird with broken figures as you constantly and uncontrollably crash.
What a shame.
