Pixelate! LDJam44

You are the only few pixels alive on a blacked out screen. Get to the goal, but a sacrifice is inevitable. Dispose some of your pixels to make platform and get to the goal.
This is my first LDJam. I had to travel and could start only today. This is my humble submission, made in 4 hours, only 3 levels (didnt do level design also, but will be updating it). Do let me know your comments.
Enjoy the game.
