Hello all, I'm looking to start running this game and wanna know what's the most optimal control style keyboard or controller or both? or is it more of a use what's comfortable kinda situation. Thanks in advanced

Awesome that's what I needed to know, thanks.

For mashing you can use a controller if you feel comfortable with it.

Welcome to Undertale Speedrunning. We're glad to have new runners join in on the fun. Keyboard is currently the best way to play the game, controller is optional/preference. You can use both at the same time too if you find that to be of good use. Feel free to join our discord and throw us some questions at any time!
