Amusing enough.

Needs polishing for certain - Make the graphics a little slicker, maybe speed it up to make it more challenging.. Like bullets are in other such games.

But you probably don't intend to work hard on this one. o:

very well done

... I did encounter a bug though... the pop up that says "Research Mines.... You need more Money $400" remains on screen even after the wave begins and then never goes away... it's distracting...

This ought to be easy to fix and beyond that I found it a cute little game and consider it well done.

Great work1
