A cool concept that may have started reaching for the rage deep in my heart. I struggled ALOT with the final stretch of the game (where there's two columns of horizontal platforms with a large space in the middle) and to make it worse, I messed up on the very last jump before being free and had to start that section all over again.
The art and music are great tho! And the mechanics vaguely reminded me of rocket hopping in Halo 3.
The only suggestion I can really give this would be to add a "shots fired" counter. Could make for a cool way to encourage replaying it while trying to one up your friends.
