Overall, I liked it! For a jam, this is great and what a jam is supposed to create: a nimble project, not to be taken too seriously, that entertains for a short while, and that clearly shows that it was made by people that had fun making it!
Of course the writing (of dialogs and events) is improvable (for example there are too many "Alright" and generally is hasty) but again, it's understandable for a jam.
I didn't get why you pass the final fight by saying the truth. Maybe you didn't convey too well that the main character it's a detective, a "man of the law". Maybe because of the hasty writing or its look too punky (it's a jam, so it's forgiven!). However it was the best part because it's where the humor really kicks in! (I loved the AutoMoles!)
And of course, the arts are top notch! Not just by their technical quality, but the character desing too! A nice touch was that singular frame (only one, pity) where the tail lights when he's shocked!
Good job! :)
