I think I can now officially call kitty boom a game! I have added Kitty’s death into the mix which means the previously ever expanding score now means something.
While looking for a (relatively) cheap way to add a rainbow overlay effect after running into some issues trying to fade in many openGL effects I discovered I could use a small multicolor sprite and blow it up to screen size allowing it to distort (I also rotated it so it stayed a bit random), then I just used a hue blend to mix it all together. I’m sure variants of this technique could be useful for a lot of ambient effects.
Also I think I may have Kittys burned into my retinas..
