Up down left right/WASD to move, and space to slash.
(Music: Last Battle, from Cave Story soundtrack, By Daisuke "Pixel" Amaya.) I had to think of SOME birthday present. Some inspiration (Although nearly none.) From Levi's Quest by Will_Wam. UPDATES: 0.1: You can walk around and slash 0.1.5: There is a boss. 0.2: The boss has dialogue and I thought of a plot for the game. 0.2.5: After going under 667 hp, the boss goes up to 666, and has more attacks, than just ramming into you. 0.3.5: Cleaned up some things, first stable release. 0.4: Added another stage, and made a victory scene
