Truly Excellent

You're a talented boy Harry

Meh

Animation poor. Jokes poor. What else needs to be said? Oh yeah, the sounds sucked as well.

Poor execution

A nice concept but certain problems make it alot less than it could be. I suggest you remove barrels as an item because it is exceptionally easy to just barrel yourself in and lob grenades over indefinitely for infinite score, rendering the high scores useless.

Some enemy variety would be nice as well, possible bosses. Has good potential though.
