Thanks! I'm glad you enjoyed the interactive-ness of it :)
With regards to benchmarks, this one was about 3 days of work (about 8 hours per day), as I also had another entry for this jam. That one was about 1.5 days of work.
90% of the time spent on Beatcore was drawing the artwork for the scenes, and also designing the timings. The actual game's code is very minimal, like, draw_background(), draw_pucks() lol
