This game does have potential, but there is a reason most tower defense games have upgradable towers. Instead of only having towers that die after a very brief amount of time, it would be better to allow the player to upgrade the towers that they already have, so that they last longer and are stronger. This also helps with another issue. It is irritating to have to constantly replace old towers AND decide where to place new ones at the same time. It makes the player too busy to focus on the strategy, which is not good for a game in the strategy category. The idea of having one stage and many waves is great, and it's fun to try to get further each time you play, but the game was very hindered by the fact that the towers constantly disappear.
