Supercool to move the key that you use and the slow down when you move the button.
The screen get a bit busy in later levels and i dont know if it was an and so i quit. Very fun to play tough.
Design 3/5
I could get to a certain point but then it got to busy to see anything
Adherence to theme 5/5
Only being able to use one button makes for some great scenarios.
Originality 4/5
Ive seen spaceshooters like this but never have i even thought you could make something this clever with the spaceshoter concept!
