You can move around with arrow keys and interact with objects by pressing enter, which is the way the game is intended to be played. The engine I use automatically makes mouse play possible, but it is in no way optimized, and I'm considering turning it off for future games. I ran out of time to put in a gameplay instruction screen because of the initial jam deadline, but I'll put it in the game description on itch.io for now. Thank you for the feedback! :)
