A nice, simple concept. I like it!
It really feels like it needs sound. I also ran out of time for that, so I understand, but it does feel a bit flat. The confetti burst is a good reward for saving a lemming, but I want more!
The lemmings seem to fall off the cliff even when I'm holding them, but I don't lose if that happens. That was a bit odd.
I like how smooth the character's animations are, and I love the cute little lemming faces.
