I made it too the moon! And I submitted my time? I tried to? I pushed the button, but I didn't see what my time was or if there was a leaderboard or anything. There was little notification in the top left about not being authenticated.
Anyway, this was great! It reminded me of a very old web game called Double Wires which I used to play over and over despite having far less content than what your game does.
My brain really isn't capable of alternating limbs with the mouse buttons well, so I feel like I passed the vast majority of the sections different than intended. The only area which gave me genuine trouble is the long stretch with spikes to either side. And, speaking of those, I really appreciated the checkpoints.
The music is great, the whip-like sounds of the arms are fantastic. The voice is fun and funny. (I did start to wish that spikes restored health...)
