I feel like I've proven level 21 to be impossible. I'm sure I made an error somewhere, but this is the point at which I would use a walkthrough if there was one.

You probably switched to a house with negative research rate. You can either deal with it by building up research through other means or switch back.
There seems to be a bug. When I remove items from the boat, they do not stay in my inventory. (in the boat screen they are in inventory, but not in the inventory screen)
I'm repeating myself here, but the items go to the warehouse. It was a bad design decision, I didn't want you to be overburdened with all 5000 weight from the boat in your inventory, but it was confusing. I'll give you the option to put items from the boat into your inventory or the warehouse in an update tomorrow.
Every time I get the popup from getting a letter or getting an upgrade, the game freezes. Restoring from save will work, but I don't want to deal with the game freezing anymore, so I am done.
Level 15 is impossible. Any hints?
BTW to everybody who complains that snipers are useless, and to everybody who complains that their units shoot farther:
Snipers shoot SIX levels. They are amazingly useful against ranged units and towers.
The developers of this game PAID Kongregate to put it on the first page.
That's how this Demo with (at the time) virtually no plays got on the main page.
