The first levels made me think this was going to be a bit boring ^^... But new mechanics were introduced nicely and the game really "took off" from there.

Simple but effective game design !

Good presentation.Well done company logo. Stages are quite creative and made good use of the partial presentation of the mechanics. The purposefully simple art of the game has given it a special taste, although it has manifested itself powerfully by crashing a ship and blasting particles. For a project done in 48 hours, the biggest problem is not having more playable stages. In time, I suggest 4 things: 

1. Create more levels in the near future. (I want to play more !!!)
2. Review letter spacing (too tight texts make reading difficult for tired eyes)
3. Try the webgl version of Unity (I liked the game, but seeing it's presentation gave me a feeling that it could've an equally enjoyable experience if one didn't have to download and run such a small game from browser)
4. Create a screen for when the person beats the game, show in how much time he has achieved, as well as the number of deaths. it would make it a lot more fun to show to friends.
