Thanks for playing and the feedback.
I agree, it needs a scensitivity slider. The going through enemies is a littler hard to fix since I think its a problem about speed, and with the mouse you can technically always go faster.
Its definitely not a long game. I personally had this movement idea on my list for a long time now and just wanted to get it out there. Might use it again in a future project with improved features, and maybe even an alternative keyboard control.
