at the end of the game, you're like invincible, it's as if they're like, punching at a brick wall, so I just yell "death spiral" while shooting randomly in a circle all around me.
A tower defense game should be about defending a castle with towers, not space marines. Telling him where to go takes all of your concentration and it becomes less and less about the towers and more about telling him where to go. If he weren't a complete retard and could find his own way around, it might be a decent game.
Are you sure those creeps are actually moving forward? Are you also sure that the tower is doing anything? Are you sure you can program games?NO,NO, and NO.
