This was a pretty straightforward game, but I still had a blast playing! You had to be careful in where you threw your arm and positioned yourself, as if you weren't careful then the enemies could manage to get a good hit in. The bulk of the game centered around the mechanic of smacking enemies around with your projectile arm, but there was a platforming section that I found interesting (though I misjudged the distance and my jumping height a few times and leaped to my doom, haha). I would have loved to see more levels like that, but even without it it was still fun! I also agree with other comments that the addition of music would have been great.
It was a fun, fairly chill experience, and I had a good time. Nice work!
