Duoism - The Balance between Light and Dark.

Yin and Yang. 

Rage and Love. 

In the eternal battle of opposites, one shall not forget the dependence on one another.

Experience duality with one of your friends. Get together on your couch, take your controllers and fight together in an everchanging world of light and dark.

The game is intended (and recommended) as a two player game, but you can play it as a single player if you really want to.

For each player, you need an Xbox-like controller. In the menu, just move your stick to join. Click on one of the buttons to select a menu item. Start the game!

In the game, you move with the left stick and aim with the right stick. You shoot with the right trigger. Explore the game and have fun!

Keyboard and mouse control is possible but experimental and only possible for one of the players. Join the game by pressing any key. Start the game with [Enter]. In the game, you control your player's movement with [WASD]. You aim with the mouse and shoot with the left mouse button.


The game is available as download for Windows and Linux. Or you can just play it directly in the browser.

So, keyboard and mouse control are experimental. I'm experimenting like mad, but no cigar :-) Which buttons are active for keyboard and/or mouse?

Hi there!

[W],[S] should be up/down in the menu and [enter] is accept.
[W],[A],[S],[D] + Mouse should work to move and shoot.

We didn't have much time during the end of the jam and very quickly implemented keyboard+mouse controls:(

Now also part of the instructions above :-)

Not even worth a reply? No worries though, today it was working. Not sure why nothing seemed to work yesterday. Nice game. Play really nicely. Also like that it's vector based, images stay razor sharp when you go full screen.

Did I not reply? I think I did. Anyways, thanks for playing, I'm glad you liked it.

Haha yes, you did, yesterday, but two days ago I saw some replies on other people's messages, but not on mine. I felt left out ;-) But no worries, it worked like a charm now!

Oh, I'm sorry about that.


Awesome! Definitely a ❤️ for you.

Thanks :)
