Plenty of potential
I'll have to agree with Runescape-Rules down there, the voices are very hard to understand (and, again, not because of the accents). They were very "tinny", and audio was pretty inconsistent, e.g., the sound of rounds being fired from the crotch gun were very faint as opposed to how they sounded when they pinged off the shark.
I found the whole coffee theme a bit corny, to be honest, didn't seem very relevant at all. But there's seriously a lot of potential here, and improving voice quality should help heaps. Great illustration style, love Jezza's design and voice, and the occasional winner one-liners: "I can tell by your ear piercings that you're up to no good."
Looking forward to part two!
