the fact that it over saves your game is a fail idea. Autosave is nice, but if I forget to do something like a repair, I'd rather not (and won't) go through 20 levels to get to where I was at again.
Yeah...started out with the ranger and failed first level...those 'big gun's kind of suck right away..needs some tweaking on balance to make it more fun I think (and I did play this quite a bit), a little more cash flow could help. Cool idea and fun though...
