I'm very happy to see that people like yourself are excited for future features!
This game was originally designed to be played with a custom input device, but we couldn't finish building the prototype for it due to the Covid-19 situation (and we obviously can't provide it through itch.io anyways). We tried to make the controls as comfortable as possible considering it's a keyboard. If you have any other feedback we'll be very glad to hear it!
