Ok, this was super cool. I love my little rat-mobile. I eventually died on both runs because I got cornered but it made me want to play more. It took me a bit to correlate the pips with the upgrade cost but it clicked after a bit. Everything you need to know is available in the vehicle which is a fun way to have the UI and keep it all in the world.
The only thing that I really had a problem with was the very beginning and trying to figure out where the claw was because I pulled on the lever on the wall and I assumed it would activate the door behind me so I didn't notice the claw drop down to my left so I was stuck for a while there. I also didn't see a menu come up when I died. Anyway, it looked great, felt great to play and was fun!
