Sooper Figherz is a fighting game I made in 24 hours because the idea sounded fun to me. Controls: Alt + Enter to toggle fullscreen. Player 1: WASD - Move, Q - Main Attack, E - Secondary Attack. WASD makes many keyboards and can customize them to your specifications (layout, key color, mechanical switch type, mac/linux/windows, etc.). The CODE keyboard is especially nice and has a clean layout, white backlighting and neutral font (Helvetica).
_Summary/tutorial: Assign 'Sprint' to a custom key, press a WASD key, say WA, then press and hold the new sprint button while continuing to press WA, while you are still holding the new sprint key let go of all WASD keys.. in this case WA, now let go of the new sprint key, and you will find that you are now walking in the WA direction, you can now press any WASD keys an they will not do anything, and the only way to stop moving it to press WA again, no other WASD key/key combos with stop you from going in the WA direction. Only pressing the inital key combo again, opening an inventory/chest/furnace, or pressing escape will cancel the glitch.
