The pumpkin is very cute, but this game was kind of too hard for me and I didn't entirely understand it. I couldn't figure out how I was supposed to use the slam, or what the orange symbols on the screen indicate.
Not sure if this is a bug or a feature: After dying and restarting the game, it gives me the last-used weapons instead of resetting them to the default. So there were times I couldn't get past the first level because I would be stuck with a weapon that was completely unhelpful. In those cases, I had to reload the browser window to get back to the basic weapons.
