First, a rant.
Maybe the random button was too random. It is a very neat concept but when the D key or Space key was disabled for 3-4 times in a row it went from challenging to frustrating, especially during the boss battle. I was able to avoid some damage, but it quickly became impossible when my Space key was disabled for many turns.
Rant over. If your goal was to frustrate, well done. It certainty sparked and emotion. :D
I liked the boss and I did like the restrictions that disabling the controls put on me, but having more options (and possibly not continually restricting the same key over and over again) would have made this game much better.
I can see the potential in this one.
Edit: One more thing! I also liked the mechanic of when getting damaged your character popped in the air which made it so if Space was disabled, you could sacrifice some life to pull off a huge jump.
