Fly your spaceship through various obstacles categorized in 4 worlds.
Extremely crisp controls, optimal for keyboards.
Music is okayish, could use some more energy often too slow and soothing.
The perspective often leaves you with an unsafe feeling because you
cannot clearly see where blocks end.
This game forces you to perfect your hand eye coordination and at the
same time trains your periferal vision too see whats coming up while
focusing your ship to not touch walls or holes (or vice versa).
Offering easy, normal, hard and extreme difficulty, there is something for
everyone out there. I managed to beat some extreme levels but could
only proceed if I'd play and learn those levels many many times.
