The humor and difficulty really clicked with me, and I would love to see more! Seriously, all the characters seem really well designed and the art fits super well; The background was a lot more fleshed out than similar games too. The controls were pretty smooth as well, but I think they'd translate better to a controller than keyboard/mouse.
Just a couple negative things: the blood lasers could use a little work graphics-wise and a few pits near the start seem like should have spikes but don't. Also the lack/increase of capitalization/punctuation on certain characters is a good way to differentiate tones and mannerisms in a limited environment, but when applied to the main character it gets a bit old fast. Really these are just super minor nitpicks, overall this was lots of fun.
...Seriously Jack? Why did you decide to hide in the single hardest spot to reach in the entire manor?
