I don’t have an Android phone, so I played the WebStart game. Maybe things have changed, maybe not, but this is my opinion about the WebStart game:
I noticed there that the ‘lives’ are really annoying. You progress throughout the game, and then it’s ‘game over’ … you have to start all over again, while the game is rather… hard, and timing is critical, so mistakes are easily made.
Wouldn’t it be much better to have infinite lives, so you can keep playing, even though your score might get decimated by ‘death’. Especially if you want your players to pay for your game, it’d be a good idea to minimize the frustration you create by throwing ‘game over’ in their face every few minutes.
