Thank you for playing. The game morphed quite a lot from the original idea, so I'm glad that it was somewhat cohesive. The original idea was a take on snooker crossed with tower defence. But it was really slow paced and I had (and still have) issues with the bouncing not being consistent. So it didn't pan out and changed into what it is. The path finding is still a remnant of that.
As for the visual indicator, I agree. Even a little bar at the bottom would've made all the difference
