I love love love this. It's quite hard, took me a while to get the hang of it, but then having the shots line up with the music and taking out dudes to it releases so much dopamine...
Some details I noticed that could be improved:
- once you get too close to the edge, in some cases you have no way to get back to the crystal as you can't move the cursor far enough away to make an impact on your speed
- you could remember the last name submitted to the leaderboard so I don't have to fill it in every time
