Flappy Rocket

The first Flappy Bird-style game I built was a one-evening experiment to see how cleanly I could replicate that famously brutal jump physics. Flappy Rocket is the same core mechanic — tap to thrust, gravity does the rest — dressed up as a tiny experimental rocket flying through plasma fields. The big change from the original is the three difficulty modes, because making everyone play on the only-true-experts setting felt unkind.

The trick to surviving past the first few gates is to not tap rhythmically. Your instinct is to set up a steady beat of taps, but that locks your altitude oscillation to a frequency that almost never matches the gate spacing. Instead, tap reactively — let the rocket fall further than feels safe before pulling up, because the cost of being too low is a soft re-aim, while being too high means you can't dive in time. Voyager mode lengthens the gate vertical, so use it to learn the rocket's exact arc before stepping up.

What's hard about Flappy physics

The hardest part isn't the mechanic, it's the feel of the tap. Too much upward impulse and the game feels floaty and easy; too little and players bounce off and never come back. The current values are tuned by playtesting with Josie until she stopped throwing the iPad. If you like one-button arcade pain, Flappy Dunk on the site is Jacob's basketball spin on the same idea.
