I actually didn't realize that Detective Grimoire: Secret of the Swamp was a sequel to an original flash game. Luckily, I already had flashpoint installed, so I figured that checking out the original likely wouldn't be a waste of time.

Yeah, this is definitely a flash game alright. Animations include a lot of obvious tweening, the voice over has a couple of Newground's elites, and the gameplay is very simple. Honestly, for the time and environment that it was made in, I think it works rather well.
