I am glad you liked the sound.
I picked arrow keys because not every keyboard has WASD in the same place.
I have updated it so you can now use WASD to move if you want to give the game another try.
Collect Blue pills to get faster, collect red pills to gain projectiles, space to fire and survive as long as you can.
I would have liked to put more information into the game on how to play but I simply ran out of time.
Thanks for your comment. :)
