Also once i realised your hittest method was rubbish I just shot everyone straight through the wall by holding down the left mouse, moving it miles away and then releasing the shot fast enough it jumps through the wall.
After looking at the stash for ages and searching the islands I finally got an objective to find something to lever the stash open, but even now there is certainly nothing clickable around. Gamebreaking bugs = 1/5.
The way you can only have one missile at once is retarded and means you fire much faster the closer enemies are. Sounds are annoying and this isnt really any different to the shootorial...
Very cool. I dont think I ever saw a health pack though... plenty of bonus things, but never anything that actually gave me more health. Surely there should be at least 1 per level?
The reload on the rifle is unbearably slow at the start. Defending the scientist and the medic is frustrating because in the first couple of waves they can be overwhelmed by zombies and you cant directly do anything because your weapon is so crap...
You need to normalise the direction you send the shell in. At the moment the shots go faster the further away the mouse is, and can get fast enough that they pass through the targets. Also a bit laggy on the controls.
