Hello guys!

This is the first game of our studio and we just released it on Play Store. Lighty Ghost is a little game where you need to touch the walls while avoiding to touch the spikes. The longer you stay alive, the bigger your score is. The little detail is the "green lights" multiplicators that encourage you to take risks in order to have bigger score. We already planned to launch on iOS when our account will be validated and to integrate a leaderboard (certainly based on facebook accounts) to compare with your friends in a version 2.

We need advices to make the "green lights" multiplicators more understandable in the game. A lot of people think for the moment it is poison. Moreover, when you take a multiplicator, the next one will multiply by 2 again until you reach x16 which is the maximum. We tried to make it understand by adding the bubbles on top of our character and make the tail bigger each time. Do you have advices on that?

Same for the gems, it is to buy characters. An idea to improve the understanding of this part?

Thanks guys!

The green things do look like poison clouds.  Making them more solid (a more defined shape less shrouded in particle effects) will make them look more like a collision object, and making them round will contrast them with the spikes, making "don't hit the spikes but do hit the green things" more visually apparent.
