Great game, thoroughly enjoyed it. I liked that my guns really felt part of the beat as I added more.
I normally try to find some constructive criticism to add to all of my game jam comments, but I don’t have a whole lot to say! If anything, I think it would have been neat to see my weapons represented on the timeline just to see how crazy it gets as it gets further.
We went with a repeating audio loop as our core gameplay mechanic too, but ours isn’t player authored – it just varies per level. Check it out if you have the time, I think we were trying to do the same thing with the theme (but in different genres).
Overall, great job!
