Hey, sorry to hear that! We had to weigh our options for the game jam environment and keyboard controls didn't quite make the cut, unfortunately.
It could be possible to add it sometime in the future, but our programmers are currently taking a bit of a (well deserved) break as we get back into the swing of our classes, work, and other responsibilities.
Keep an eye out, though!
EDIT: Download the newly uploaded post-jam version! Keyboard controls are now in, but the UI is still the same. Bindings are listed above.
