Duality is born! You are an unholy abomination, angel/demon hybrid. Use the portals to switch planes of existence and overcome the enemies and obstacles! Duality is a 2d platformer written in Go and intended to be played in the terminal.

Check the source link for installation instructions or download Windows version! This is my first anything in Go, so the source is horrible. Sorry!

Im well aware about difficulty with the controls and im sorry about that! Best idea seams to be tapping repeatedly and not holding the button. Its all due to limitations of terminal input. One button at a time and delay while holding button down. Its fixable, but not in the given time frame, sorry again!

Again, im terribly sorry about the issues with the controls, but it is a system setting and beyond my control. There is a way to improve this. On windows you can decrease the delay:
Control Panel -> Keyboard -> Speed -> Repeat delay -> Short (About 200ms delay). There is no 'No delay' option. Im sure there is something similar on unix systems!
