disconnects count as a loss to prevent abuse, since players can just disconnect on purpose to face a lousy ai, or disconnect to give people free farms without losing score.
(cont.) The first few levels are the most difficult due to the low speed. While saving for the best weapon/bow seems like the most cost effective, in the end you have more money than you know what to do with, so you might want to buy a better close range early in the game to prevent being swarmed. Later in the game and with better speed, stomp+bow makes zombies a minor nuisance.
The number of crates that spawn every day is always 5. The placement and number of ore/lumber is always the same every day, though sheep seems random. Crates that spawn in the center area are always normal crates; crates with metal corners spawn after the boat/bouncy spring area and gold crates spawn after the bridge. Iron crates take the same number of hits but give better loot than normal crates, gold crates has more hitpoints but gives a lot more loot.
I think that the arrows launched from the crossbow should be fired one after the other rather than at the same time -- it may not make much difference damage-wise but a continuous stream of arrows just looks awesomer.
The controls are still freaking sensitive even after upgrading over level 5..not to mention the checkpoints being useless and the AI sometimes taking the wrong route and being teleported back.
