Don't carry on when the level's already been lost
The music is cool.
Fun game and I liked the aleatory element - a value underlooked within games.
Though the inspiration is obvious, the differing method of progressing reactions helps it stand apart.
I only got to where the blues are reintroduced (after the yellows) - having to avoid them made for a frustrating pause when the game was already lost, but the chain reaction carried on anyway. Also, I felt that for what seems to be an almost-entirely luck-based game, the difficulty was a bit high. I felt dejected more than anything.
Regardless, not a bad game - original enough - and I'm sure a few tweaks would help it be more relaxing and less furstrating.
