Nice idea, top-down shooters are always a good option. However, the controls are a little weird. Loved the minigame in the game, but also there controls need some rethinking. I understand the idea of moving around the cursor, but it's really difficult to adapt to it. Also because the "main" game works the opposite, you move with respect to the camera, so switching is difficult! And some music and SFX may add a lot to the game!
Nice done!
