Totally love it but..
I find difficult to shoot so many beasts with using to mouse to shoot.
So you could change to control for shooting to spacebar etc...
Like also we could save the game.
Hope that you could also add more ships and the ships has pros and cons
Etc.
Shipname: Lightning runner
Pro: Travel like the speed of lightning
Con: Defense reduces by 20%
Good luck on improving the game!
Hope to see more games form you!
