It's an unusual kind of space shooter. You basically have to shoot at Blockers in order to stop their movement , but their stopping angle is very important. If their angle is below a certain limit then the Blocker will expand and block the electron barrier which will otherwise electrocute you if it remained unblocked.
Unblock all blockers and you clear the next level. The closer the Blocker's stopping angle is to the perfect angle the better the score and the more stars you will earn.
It took 10 months to develop this game using Libgdx and Blender.
