Heroes by Design makes its Android debut this week with the release of Asterism, a free-to-play physics puzzler that includes 60 levels.

Asterism challenges players to eliminate star clusters in each level by aiming and rebounding a limited number of shots fired from the bottom of the screen. It's a simple but neat concept -- it sort of reminds me of the early iOS hit Orbital, mixed with a dash of Puzzle Bobble. Try it out!
