So I think you lose your colours once you collect more than 4 total. You start with two, and you absorb the colour of any fish you absorb. Not quite sure how it all works, but that's what the source says.
The arrow key commands feel a little funny to me, they turn the fish to swim towards the direction you are pointing. I would much rather use left/right to turn and up to go faster. The down key wouldn't need to be used, as the fish slow down automatically once you release the up key.
It's a nice relaxing game, works relatively well with just a trackpad too.
Tried it on a phone with Firefox and Chrome browser. Works fine directing the fish with the finger - though sometimes you do not see the fish because of the finger. Maybe using inclinisation of the phones to direct the fish is a better idea - kind of like doodle jump.
Biggest problem with the game is that the sizes are too close. Several times I assumed i was the same size with more rings inside of me or even bigger than my prey but the fish i touched actually killed me. Too confusing and obscure currently but the concept is great.
