Thanks a lot for your comment, and especially for taking the time to finish the game! It really means a lot to us.
Our main goal for the jam was simply to get the game finished and playable before the deadline, but the idea of turning it into a proper mobile game has always been in the back of my mind. That's also why we went with click controls, since they translate well to touch screens.
That said, I completely agree that for the PC version, supporting WASD/arrow keys would make the game much more comfortable to play. We went with the simplest solution we could during the jam, but it's definitely something we'd like to improve.
Thanks again for the feedback!
