Tried to play but couldn't progress much, the action keys being under the movement keys doesn't help much.
The game also works with a controller if you connect some to your computer. Sorry that the layout doesn’t work for you.
Tried with a PS4 controller, much better now :) The guy on the right does not attack, and after beating him it took me to the Restart (doesn't work) or exit screen. Just the one level for now ?
Yes just the one. And right does not attack since it's setup as a two player experience.
