Cool game ! The concept was really nice and the game itself is polished =) ! The music is cool and I must admit that the boss music, even with its asiatic vibes (that were a bit out of place for a game about robots ?), was a banger for me.
The levels were either too long or lacked a timer to tell the player how much time was remaining. I almost quit near the end of the first level because I thought it was just an endless single-level.
Good job =) !
