I really like this idea! The visuals and music are simple but work really well. I found it a bit difficult- I couldn't get past the fourth platform for the life of me. I wish there was a way to either lock your cursor in or see it while playing, I kept losing track of it while aiming and ending up leaving the window - having to adjust my aim and bring my mouse back onto the screen before clicking to fire usually ended up with me overshooting.
