You need to spell out how to play this game, especially if there are any hidden mechanics. I played the offline version and beat stage 1 but stage 2 got to difficult to keep up with.
Please make the crosshair a lighter colour so it's easier to make out and possible larger (EDIT: actually, the cursor doesn't seem to resize when you go full-screen, so that's the actual problem).
While I appreciate the effort put in, it's just a precision clicker game in the end. I was expecting something more akin to "Fruit Ninja" given the name, where you slice enemies instead of just click on them.
I look forward to seeing how it turns out.
