Where can I see the actual health status of my gunship?

To Dev, Played about 4 hours now. Biggest issue for me is lack of speed up button (or I couldnt find it). I was only getting to early 20s levels but it took soooo long. That combined with the limited enemy numbers means not much cash earned so other then upgrading a tower or two between waves theres nothing to do but sit and wait for the end of the next wave. Also being able to call the next wave early would help too. Looks great and runs great. Had one crash on the 2nd level after the tutorial. ...

I'm experiencing a LOT of crashes, normally straight from opening the program... often the program crashes during loading itself, or as soon as I move the mouse when I'm on the menu screen. On average it seems to crash about 5-6 times before I can start a mission, the mission then seems to crash the game after a while (on the snow tier 1 mission it crashed my pc on wave 10, on the other tier 1 mission the game crashed on wave 3 after I'd finished upgrading everything, but before I could start the wave...) ...

Got through this level fairly easily on second attempt. Used shift key to place multiple cannons and quickly maxed damage and fire rate. Placed cannons at the top corner of first run and in the left side area where the runs intersect just before the exit. When first group of cannons exhaust their fire, I sell, max, and place on the final run to exit....
