Well, five hours ago I started work on a Defense game, which I quickly named Defend, and I've made it completely playable. Current features are:
Five waves, with four different types of enemies.
Fully completed shop, with repairs, barricade upgrades, weapons, and attack upgrades.
Fully eight-bit graphics and interfacing, which use the NES palette.
Keyboard controls and mouse controls, WASD or arrow keys for movement, 1 for handgun, 2 for uzi, 3 for hunting rifle, 4 for shotgun, and 5 for bazooka, if you unlocked the specific weapon.
Planning on adding before putting on hub:
Five more waves,
Link for it is here.
Please try it and give feedback, would help a lot.
