Arrow keys or WASD to move, space to fire axe. Currently in beta, and the full release is not going to be anytime soon. If you have comments or suggestions, feel free to comment.
0.1: Release after about a week of toying with it. Multiple bugs, as 0.1 was just a proof of concept. Update: 0.2: Slight graphics overhaul, enemy cap, toying with horizontal movement, lowered enemy spawning rates, new explosions, a song (But music not yet implemented), and various bugfixes. Update 0.3: Player loss/death implemented after many headaches. You should now fail if the player touches an enemy or an enemy gets past the player.
