I'm glad you liked it. ^^
I was surprised by how much the sounds improved the experience... Until the last day, I was ready to submit the game without the SFX, only with the music... But somehow I got inspired and was able to add a lot of sounds...
Hmm... I believed that some people would enjoy this pacing... My friends who aren't used to play bullet hells enjoyed it as well...
I think it's impossible to make a pacing that everyone likes, but your idea made me realize that there are some things I wasn't considering... Really Thanks...
Giving the player some agency to choose accelerate the process could be a great way to tone down the sensation of a slow pacing, even if the pacing still continues a bit slow.
