This was cool Philip! I think you used the assets really well and the little noise effect you got going on the skybox is kinda neat. My only gripe with this was how it's balanced if that makes sense? I kind of wish there was another arrow pointing in the direction of the closest ball, but that gets rid of the fun of looking for where the ball is. I guess the best way to describe my mixed feelings is that a lot of balls got close at once and it was hard to move fast enough when they were coming from every single direction. Maybe this is bad advice because I just get overwhelmed easily, but maybe if there were fewer directions the ball could come from that could be better?
EDIT: Ok so I went back and replayed it and I think I got overwhelmed because I couldn't get rid of balls that were too far away and I had to let them get close in order to click on them. Sometimes my click didn't work, but we didn't have much time to make these so that bug being there is totally understandable!
Either way, I think what you have was good and it's cool that there's a whole high score system too. Good job!
