equip hero/ship with item you don't want then go into shop click on the item and a sell button will appear then go back to your inventory and either equip another item to sell or equip with the item you want to use in the next battle
agree with GoeyJoe got to level 10 and showed 1 zombie left had the troops walking everywhere but no joy other than a couple of bugs this is a fun little game
good game just needs more levels and development
strange scoring shot down 6 or 7 ballons and got loads of money but only got 200 points also have put 2 arrows into some ballons and they've crashed but 4 into others and they've still rised (same colour ballons)
Added fix, it seems to work for me but I'm not getting the problem as often now. Please give it a whirl and let me know if that's any better?
