Redesign or relaunch of "Balisong knife" app from apptor (me) in the google play store Currently I am offering the app "Balisong knife" in the play store. The app is very simple and should be relaunched. Please have a look on the current app to get an impression. The new app should be a game. The knife must be thrown at a target. Control by movement of the mobile phone. Screen 1: knife is shown (already exists) by shaking the mobile the knive opens and closes and plays the sound (already exists) an info is overlayed over the knife picture: "press start for throwing the knife" after press start -> screen 2 Screen 2: Knife is shown small on the bottom of the screen the target is shown on the top of the screen. an info says: the target is 5 m away, move the mobile to throw the knife after making a throwing gesture with the mobile phone -> screen 3 Screen 3: the knife is rotating and flying towards the target making accompanied by a sound -> screen 4 Screen 4: the knife is shown on the target (either on the border or in the center of the target) an info says: "congrats you got xx points. try throwing more strongly / softly" "touch screen to throw again" when screen is touched -> screen 2 the app should by kept simple. your creativity needed. Graphics and sounds must be provided by you but should by replacable" Minimum needed quality assurance should be done by you (e.g. check if app doesnt drain the battery)
