Tappy Lander Dev Diary #4: Control

I love the mechanics of lander games and the fun, to me, is maneuvering your rocket through a series of subtle movements into a good position and a soft landing. It’s difficult but rewarding.

Traditionally these types of games had a variety of buttons: rotate, left, rotate right, thrust, etc.

However, on the target devices I have one button, the touch screen; and I refuse to clutter the screen with complex controls just so it plays exactly like the originals (see my last post about UI.)

In order to simplify, I ask my favorite question: “What makes it fun?” and my cat looks at me like “Who are you talking to?!”

What I came up with…

  • Gravity – yes, still fun after all these years!
  • Rotating – a little frustrating to manage and even time consuming
  • Thrusting – absolutely, compensating for a force like gravity or your last thrust, in order to change direction, is fun.
  • Managing fuel – no way, maybe its just me, but I don’t like time limits. I don’t want to tell a player “You know this fun little playground I made?, well you can only play here for THIS long.”
  • Avoiding an obstacle or flying to collect an object – yes! an opportunity to test your flying skill.
  • Landing – yes, slow down and center yourself over the target for a soft, safe landing.

The Redesign

I immediately wanted to remove the fuel consumption issue. This is in essence, a time limit. It makes sense for quarter munching coin-ops, but doesn’t in a free mobile game. The gameplay is not made more fun by adding a time limit and removing it allows you to focus on manuvering even if you need to take your time.

Most classic gravity and lander games allow you to rotate your ship so that you can thrust in any direction. Again, this is something that I felt I could remove. With a simple up, left or right control scheme, I can move in any direction by timing my taps (except down, and gravity takes care of that.)

A Prototype

The prototype allowed me full control over my ship and maintained the fun of using your skill and instinct to manage the physics of flying through space. It was fun but simple; easier for general audiences to pick up and play but very challenging at the same time.

…and so I moved ahead with development! The next post will be about game physics.

Tappy Lander Dev Diary #2: Influences

I played Lunar Lander (1979, Atari coin-op) for the first time just a few years ago. It made a big impression on me and ever since, I have wanted to make a game like this.


In Lunar Lander, you try to safely land on a craggy planet before running out of fuel by rotating your ship and thrusting in the desired direction.

Gravitar (1982 Atari coin-op)

Gravitar (1982 Atari coin-op)

Gravitar focuses on flying through caverns and shooting at targets while saving prisoners. It’s very difficult and even has a level where you fly around a planet with gravity pulling you toward the center of the screen.

Sky Diver (1978, Atari VCS)

Time your jump out of a moving plane and pull the ripcord before hitting the target in Sky Diver. Points are scored based on the accuracy of your landing. You have limited steering ability once your parachute is open and must take wind speed into account.

Sub-Terrania (1993, Sega Genesis)

Sub-Terrania (1993, Sega Genesis)

I love Sub-Terrania! Fly around a map using lander-style controls, shoot enemies and save prisoners-but with a snazzy soundtrack and nice presentation.

What does Tappy Lander borrow from these games?

  • The gameplay mechanics. Gravity pulls you down toward the target and you control your ship by thrusting in different directions.
  • You must not hit the landing pad too hard and more points are rewarded for accurate landings.
  • Get bonus points for rescuing floating vegetables, stranded in space.
  • Lots of dodging and maneuvering around traps and obstacles.

What does Tappy Lander do differently?

  • There is no fuel to worry about. Fly forever!
  • Controls are simplified: You can only thrust up, left or right.
  • No shooting. It’s all about precision flying.
  • In addition to touching items for points, there are items you must collect to complete a set.
  • More stuff that I’ll talk about in a future post!

The next post will probably address controlling the game and UI. See you then!

Apple Now Gives 100 Promo Codes Per App Version (Instead of 50)

Apple Now Gives 100 Promo Codes Per App Version (Instead of 50)

I just snapped this photo about ten minutes ago. I double-checked on a second app and it’s true. Apple developers now get 100 promo codes instead of 50. This has been enacted retroactively on all our apps.

This is a good thing. We have found promotional code giveaways to stimulate our sales. Win-win.
