I like it.... mostly.
To begin with, it's a very easy and quick learn. The controls are smooth and predictable which leaves continuous success or failure generally up to the player.
The dialogue was humorous, especially when the narrator starts taunting you during play. Although, I wasn't sure if the use of "gay" meant obnoxious douche, or homo. The word is ambiguous these days.
I noticed how "Normal" mode gives you a 0.5 multiplier, halving whatever score you get in the end. I personally find this to be a punishment for just wanting to play the game, since "normal" means that this is the original intended product. If you really just need to punish people, punish them for playing on easy, then make easy so stupidly easy that it's boring, like just having way too many demons falling so that it's impossible to ever die unless you get hit by the falling spike, which you can't see because the Icon that shows you where it's coming from isn't there on easy only. And, when you do die, your multiplier is more like 0.0001. It would be so ridiculous that it would be comical. Again, halving someone's score just for playing the regular version of your game is really just obnoxious and makes you look like one of the asshole game designers who shits on people that just want a casual game. If your intention was to have "Hard" be the basic difficulty as if to imply that your game is in itself challenging, then you still should have called the lowest setting "Easy". Or, if you really want to shit on people for playing on low settings, name it something along the lines of "Pussy."
