The first time I threw a tank and it kept shooting enemies as it flew gave me a great laugh. This is a pretty creative game, and it shows a good amount of effort was put into the sound. Everything has an appropriate and punchy sound effect! I had fun playing!
This game is a little difficult to get going with however, even reading the controls text file. Once I understood that you have to keep spinning your mouse in the green I was able to play, but there isn't much feedback for it before the spinning starts, or after while you charge up. I like the idea, but I'm not sure the mouse cursor circling the swing is the control choice I would have picked.
It looks like this may have been your first jam, so congrats! This is a great product for seven days by yourself! I look forward to seeing more from you.
