This is really impressive; the art style and the character animations are absolutely awesome. I played with a mouse and I was impressed how well it controlled with only mouse movement and lmb/rmb.
I couldn't get past the part where you learn to swim in a wave to go faster (I'm not sure if I was going fast enough to break the rock at the end). Also, I had a few crashes early with an error about the audio.
Keep up the good work!
