Thanks for the feedback! We had a few conversations throughout the weekend about the "beat bar" and it's positioning. We definately agree that it distracts from the actual shooting gameplay but didn't have enough time to move it somewhere else or show it in a different way.
We created everything from scratch and unfortunately towards the end we starting putting a few too many things into the game for it to handle the rendering. There are waaaaaaaaay too many loops in there (for example) that we could have been smarter with. Perhaps next time we'll use a game engine ;)
