Azutama is basically a remake of a very old arcade tank battle game. Protect your base from fellow colleagues by knocking them out using snowballs. There are power-ups to collect and mid-level bosses as well, judging from the screenshots.

The trial version is a bit on the short side but it does show promise. You can download it by clicking on the link with the largest font.
