there's a bug currently where the game might not load the second level. if nothing happens after clicking "next", you can refresh the site and it should work the second go around…
Interesting mechanic. The graphics and sounds are very barebones but I could see this mechanic working in a platformer. You'd need a little more polish on the camera side of things. I kind of get where you're going with the "find the platform so the camera angle changes" thing but it's not the best gameplay wise. I liked the way the character looks when they're swimming under the surface like a shark :). And the way the rings fly out in a circle when you respawn.
Nice work! <3
