Please redo the damage on the weapons, it doesn't make sense why artillery sucks so bad, and machine guns rip through everything. I wish there was a notification of aircraft, but I pretty much memorized them after playing it about 20 times.
It would also be nice if the anti-aircraft cost wasn't mixed up, I've payed 50, and sometimes 25 on the same upgrade.
Other than a few mishaps, I'd say the game is overall playable. If you start out with turrets rather than kamikaze motorcycles for a few waves, you set yourself up for trouble. Building money warehouses before any others is key, I'd say at first make as many as you can until you are left with 10-20 dollars.
Good luck to anyone who plays this, it's quite challenging.
