Good fun. Solid premise.
Not really bringing anything new here, it's fun, a little short, but that's easily forgiven when you're not being paid. :p
Could be a bit harder, I was level five after the second level.
On that note, why does the level icon say out of 8 when there are nine xp levels?
Anyway, good stuff. My favorite part was the ending, almost as if he were saying
"Get offa my lawn! Crazy...punk...kids"
