It was fun to play. Knocking the astronaut around and gunning down asteroids is satisfying. But I wish there was more purpose to destroying asteroids besides preserving HP and creating space. I was expecting power-ups to spawn from breaking them at first.
Also, the power-ups that do spawn stick to the right side of the screen where the obstacles and enemies spawn. It was pretty stress-inducing to collect power-ups because there was a risk of hitting something I couldn't see. I had to rely on luck each time I went in for a heal.
The game looks nice. I just like cartoony visuals.
Overall, it was a fun, short game that kept me on my toes.
