Updated version and the original version made within the time limit can be found here. http://gamejolt.com/games/rpg/wallcraft/65/ Guide to upgrades: Castle / Upgrade Guide: Sword – Strength, how much damage you can deal with your sword. Cross – Health, how much damage you can take. Raising health is the only way to refil it. Magic… thing – Magic! Does twice the damage of your strength. Magic has limited ammo and must be  rifilled at a castle. Magic can also be fired at the wall to slow it down slightly depending on your  strength. Square/Little Dude – Soldiers, they slow down the wall when deployed. Upgrading at one of these  castles gives you an extra soldier. Coin – Money, each upgrade cost 10 gold. Gold is aquired through killing monsters. Upgrades are necessary if you want to get a good score. While the enemies will get tough if you  upgrade, you still can’t last long with out them. The soldier upgrade is needed to slow down the  wall, which will grow faster than you quickly without them. But buying soldiers will still make the  enemies you fight more powerfull, so you need to upgrade your strength, health, and magic as well.
