An endless runner rhythm game is a really fun idea.
The rhythm part did feel a bit muddled since you had a pretty big window to react in. But even with that, the flow of dodge, attack, reload felt pretty great. I definitely wanted more.
It did take me a while to figure out how to reload since I didn't read the instructions in the description. I thought I had to dodge while they were going center, so I never just did nothing to get the reload. (But I also figured out that if you dodge endlessly you can get really high scores because the game doesn't speed up as quickly. I hit 400 before went back to the main page to figure out how to reload)
