My entry for Ludum Dare #34. Theme: Two Button Controls.
How to play:
There is a box above your character's head. In that box, icons will proceed from right to left. When they reach the highlighted area in the middle, press the corresponding button:
SWORD ICON: Press A to attack. Deals damage.
SHIELD ICON: Press D to defend.
DODGE ICON: Press nothing.
POTION ICON: Press nothing. Gains life.
If you do the wrong thing on any of these, you take damage.
