Let me get one thing out of the way: this is
not Flappy Bird, Crossy Road, Pop the Lock or something similar. Let me get one more thing out of the way, this is not Candy Crush Saga, Clash of Clans or Subway Surfers.
Downwell is a tough-as-nails, Rogue-like. It has only three actions, move left, move right, and jump/shoot/select – but it is far more nuanced than the aforementioned “one-tap” games and far less exploitative than a "free-to-wait" title. You have to pay US$2.99 for this game on iOS (shocking, I know) but boy is it worth it.
Downwell may look low-fi, but the colors are essential for identifying enemies. You are tasked with navigating to the bottom of each stage while blasting away the nasties in your way. Each creature you encounter has the potential to steal one life from you and on the normal difficulty setting you begin with just four of these. The enemies are numerous and varied, but to the experienced player they all pose a simple question: can I jump on them?
You see, landing on any enemy, rather than shooting them, refills the ammo/charge of your gunboots. What's more, if you fall on a string of eight or more enemies in a row, you're awarded with extra gems. These can be used to buy more health and increase your ammo capacity.
The problem is that not all enemies can be landed on without damaging you.
