The music and graphics were pretty neat!
The controls were also very fast and intuitive!
One point of criticism I found were the lack of sound effects. With just the music in the background, the environment just felt a little empty.
Another criticism I have is whenever you die, it just takes you back to the menu screen. I don't really like that in games. I would've preferred if the level reloaded immediately.
These points aside though, I had a fun time and loved the concept! Great job on this one!
