An interesting little game.
I didn't really understand the mechanics, even though there was a tutorial screen. I don't know what the energy/lightning in the bottom corner, the lucky clover or the fish score in the top right was about. I gathered that successfully getting the fish increased the hunger score in the top left, but that was about it. The sound effects and music were well implemented.
I played on a desktop in full screen, and there was a skybox around the edges of the designed aspect ratio. It would be better if it was all black or otherwise screened.
