It's actually fun if a bit campy (or because it's a bit campy).
You can taunt enemies, everything can be pushed or toppled over so you can use the environment to your advantage. They do recommend a controller but there is a list of controls if you want to stick to the keyboard.
It's not a full fledged game (playing time is less than an hour) but it's really cool.
By the end you're left wondering what they could do with a budget and enough time for development.
