A really great take on the theme. Nice mechanics overall, but it took me quite some time to realise that the location of the mousepointer affected the jumping. It would be good if the tutorial part made that clearer. It would also have been nice with power ups or something like that in the boss fight, since it became a bit monotonous to shoot the small color dots when they had so little impact on the health.
Really nice old school feel, nice solid controlls and nice retro music and sound effects :)
I didn't manage to kill the minions, don't know if that was intentional, and couldn't shoot through the "lasers" which felt a bit odd. but all in all a nice play through.
