Quite an ambitious message in a game!
The flashing images had a bit of a negative effect on reading the intro though. There were some typos and errors in grammar, too. An English teacher might be able to help you with those.
The gameplay is quite good, but very difficult. Sometimes it was just impossible to dodge a falling trash can because the player movement was too slow. Having to replay up to 6-7 minutes is a lot to ask of a player.
You've got a nice start though. Keep it up!
