I really liked this demo and totally can't wait until the full release! But i did have trouble getting past the second boss paw at the end boss battle:
What kind of trouble? Have you finished the demo or did you find a bug that prevented you to do it?
During the boss battle at the end, i couldn't get Lenin to move fast enough by pressing Z or Enter, the paw kept catching me.
Either it was the game being slow or my settings in my recording device.
