Thanks for the positive and constructive feedback!
I didn't notice the subtle difference with the red armadillos and the 3/4 timing, but your point makes totally sense.
I made an update so I hope you enjoy it. :)

There's so much about this chart that I love, but this isn't a song with triplets, so the red armadillos are either off sync, or the chart file has 4 subdivisions, which directly changes the armadillo timing. The former leads to a lot of accuracy issues, and the latter also leads to accuracy issues since most people would still hit them like normal red armadillos. It's a relatively common mistake all things considered, but it would feel so much better to play if the red armadillos were replaced with something that had 3/4 timing instead.

With that being said, banger chart. I had a ton of fun playing it, I just feel the need to comment on 3/4 armadillos since I see them way too often and they give me trust issues

Amazing! That was a lot of fun to play in impossible mode
