Here is a prototype I developed in 10 days for the One Button Jam that ended last week. Has the name says it, every game in the One Button Jam must be playable with only one button, which make the gameplay very tricky. You can play this game here : https://apprenticesoft.itch.io/epic-ball-adventure-prototype
In Epic Ball Adventure you control a ball that can roll right or left by pressing F. You need to cross levels full of obstacles. I used libGDX to create this game. The game is based on physics. It contains only 5 levels. Most of them are VERY challenging, as I didn't have time to balance the game. I'll probably keep working on this game to make a small physic based game for Android.
I'll change the gameplay to allow the user to direct the ball according on which side the screen is pressed : Press left to roll left, press right to roll right. That'll be much less tricky and frustrating.
