Since you were the first to rate me, you are the one I'll rate first. ;)
You game is very interesting. For me the theme is respected, having this gigantic astronaut trying to save tiny towns on a tiny planet. I like pixel-art, I had a NES in my hands, so I like it
The controls are simple yet hard to use, because when we are upside down, the movements are backwards ! I ended up jetpacking all the time because it seemed faster. Maybe a fuel gauge that would allow to take off only when it's full would prevent this and add more challenge (it's already challenging). Still, the asteroids have a high tendency to spawn on the other side of the planet and to fall very fast, which is frustrating when 2 cities are erased without any chance of salvation.
The sounds blend in very good. They're not too many and well chosen. I was upset when I stomped on the first city, hearing the shouts of the poor citizens. :( A small alarm sound when an asteroid is about to land would not have hurt, IMHO.
The music ... is ... great ! Spatial and with a sense of danger. Really good choice ! Did you get it somewhere or did you compose it yourself ? I love it, I'm ready to listen to it much longer.
Thanks for the game session. See you on the next jam !
