Jumping Man

Structure

Truncated name makes the app look unprofessional before it is even started.

Use a square launcher icon.

Canvas orientation is wrong.

Correct canvas orientation

Button sizes are too small. Minimum touch area is 7mm x 7mm.

7mm x 7mm, 1mm margin 37px x 37 px, 5px margin

9mm x 9mm, 1mm margin 47px x 47px, 5px margin

Add touch down feedback for all touch elements.

Mockup

Use the hardware back key instead of pause/back/exit buttons on screen.

Keep response times short.

The ads are placed well, but do not show ads in the game canvas while playing.

Set the game sound to off when opening the game.

Do not link to broken webpages.

Finger hides the coming gaps.

The game idea is good.

Improve the feedback.

Sky Sudoku

Structure

Splash screen is usually with little information and of no use.

Do not use abbreviations. People will not understand your app.

Do not use brackets for commands. Text becomes hard to read.

Bold typeface is not good enough as an indicator.

Describe all features and all possible values in the Help section.

Dialogs should not be cryptic but crystal clear.

Do not use LCDUI Dialog for Help or About. Use the TextBox instead.

Do not set a highlight or an indicator to any field which people cannot effect.

LCDUI’s multiple ChoiceGroup does not work as switch metaphor in Nokia Asha.

It is too easy to (re-)place a number by accident.

Check state requires an “uncheck” state, since you toggle a state not a view.

Quicksavekeys do not work as there are no hardware keys. Save in background.

HW Back key must exit the game from the topmost hierarchy level. Always.

Remove settings to reduce complexity.

Remove hierarchy levels to reduce complexity.

Free the canvas from options menu and gain screen real estate for main controls.

Proposals for redesign

Simplify the game canvas.

Reduce the options.

Direct people from your game to your web page.

Sell small batches of games with a low price.

Proposed structure.

Proposed interaction.

Make sure the pocket knife fits into the pocket.

Each setting is a decision you were too much of a coward to take.

UX offering

There are LCDUI and LWUIT UI style guides.

There are UI stencils for Inkscape in addition to Adobe Illustrator.

Asha UI component demo application is a Java midlet suite for LCDUI.
