For anyone rating this game, I'll explain how to play here:
The first button - for building towers. Press it to bring up a menu of 3 different options
The towers - once you're in the menu mentioned above, you can either pick a normal wall, ranged tower, or melee tower
-The normal wall is a high-defense, low-offense (it has no attack power)
-The ranged tower is a medium-defense, medium-offense, and can attack from a distance
-The melee tower is a low-defense, high-offense, it does massive damage, but can only do that damage once an enemy is touching it
The second button - the wave start button. Press it to start the next wave (it won't do anything if you are currently in a wave)
The third button - The settings menu. This button is unimportant, and does nothing.
There are 10 waves of increasingly more difficult enemies, and if you make it through all 10, as long as you have a tower remaining, you win! If at any point you have no towers remaining, you lose! If you lose, check the terminal which opened with the game.
Have fun!
