First things first, the art style on this game is quite unique and cute. It gives off this nice hand-drawn feeling to the game without feeling too cluttered or messy.
The game itself is interesting too. It reminds me of Missile Command from the Atari 2600 in a way, except here you have less control over the direction of your rocket, which complements the damage increase gimmick quite well.
The only thing though is that the audio doesn't seem audible on my end. I'm not sure if that is caused by a glitch or if you weren't able to implement it on time, but overall you still did a solid job with this game!
