Props for making something more unique. Everything about this game is really interesting from the sounds to the graphics. It shows that you really did think about the theme.
I found the spear to be an excellent weapon of choice. One not often explored in games. Also the big blue monster is quite funny looking, just saying.
As far as aesthetics, it's really cool the way the pixels kind of warm around the planet... I like the old school tv effect as well. Nice textures I guess would sum it up.
Need to come back and learn more about the flowers and how to make the planet turn green though...
