Notebook Wars Saga.

This cute little shooter is an arcade shoot-um-up where you are a pilot who has to literally erase the bad guys. You click an drag your mouse to control your air craft, all wile  shooting enemies and avoiding their attacks.  There are a few issues.  all coins have the same value. You can't speed up the long, slow levels. The perfect bonus at the end of every level is the same 250 coins (so it would take about 40 of these to buy a decent weapon). Some enemies are the same color and shape as coins. Worst of all, you not only have to hold down the mouse button to fire, but you can't move unless you're firing. The lag between mouse and aircraft, no auto fire, no drops, no differing level difficulties, no distance meter, no keyboard shortcut for bombs. It just feels slow and laggy.
