Hey @GTGJon hi.
The animations of the enemies the graphics and the music are well made .
I like the music of the game, one thing only (maybe it is me ) lower a little bit the volume of the sound fx .
Ahhhh at the beginning of the game do not put so much enemies, let the users to get use the control system of the player and to be comfortable with that ,because if the users loses over and over at the beginning of the game they soon get bored and eventually they will not have a motivation to continue playing.
Other than that your game is playable and funny (and with a funny script).
Keep on creating and good luck with the upload.
