Really cool and well presented.
I do wish what I was shooting were not spherical targets as it felt frustrating when bounces weren't going the way I wanted them to. I bet I'd like it more if they had clear sides to them, as well as the ability to rotate them.
Then again, this is clearly a skill issue on my part. (I also had no idea what most upgrades were doing for me, but I bet re-playing it would shed some light on them).
Well done.
