This made my tiny, smooth brain hurt! But in a good way :)
Really interesting take on the theme and on the classic tetris formula. I had fun with this even though I'm terrible at it. Super cool idea, and I love that it's just a simple idea executed well, rather than trying to tack on a bunch of stuff.
The sound design, music, and graphics are also on point. Nothing fancy, but I actually appreciate the simplicity, and it definitely scratches that 90s-nostalgia itch. One thing I might have liked is more visual feedback when a ring disappears (maybe briefly highlighting them before they disappear or something like that), but that's a nitpick.
All-in-all, this is a really great jam entry, and one that I could see myself coming back to and recommending to some of my Tetris-obsessed friends. Also, love that this was made in LÖVE :) Great work!
