Haha, thanks for playing and the feedback! :)
About the background, I ran out of time and energy to make it more creamy looking/put a white or black layer with opacity so it doesn't look too heavy on colors, and in the boss I forgot to turn off the animation to reinforce the endurance situation. (At times I think I put many stars in the background hahaha)
And about the Calm mode it’s ok, I think I couldn’t express well what it does and I put “press X” instead of “hold X”, also I think it’s a mechanic that is better explained in a tutorial than text, which I couldn’t make for lack of time, but I’m happy you tried to use it ^^
It’s supposed to be a slow down in the movement in case you want to cross between bullets and after some time, you get slower , which is a rare case in this game since those only aim at you and not like other shmups where you need to cross between close spaces of bullets. And also gives you a boost in the shoot speed, which is useful when you have bad RNG and get only green orbs
