Neat simple little game. I liked the lives system (I want to add one to my own game at some point). It would be cool if the game sped up over time, and maybe more colours that were introduced later in the game (i.e. you start with 3 colours, then at 10 points you introduce another colour). I played until I gained a score of 40 because it started to feel a bit stale. Maybe different icons (e.g. gems) instead of colours and a moving background could be cool. Sounds effect would also be appreciated.
