I played it until I found out that punch and kick were bound to mouse buttons (so, not very long). This control decision makes the game nearly or completely unplayable on a laptop with a trackpad depending on that trackpad's behaviour, and doesn't provide any benefits over a fully-keyboard control scheme.
The mouse has a particular use - cursor control (ideal for interacting with objects on screen, aiming, etc), not simply a stand-in for the button part of a gamepad, and using it just as a trigger not only is an inappropriate control choice, but one that hurts the playability of a game that doesn't inherently require the control a mouse provides.
