Cool visuals and interesting patterns! It was fun to learn the way to avoid each of them. However, it got quite repetitive after a while, I ended up just killing myself at around 200 seconds. I think it would have been a great improvement if patterns got harder over time, or if new variations of patterns started coming up after you’ve been playing for some time. The music loop was also a bit too short and got repetitive after a while.
But in any case, overall it was an enjoyable experience, good job :)!
