Thank you, and I like your suggestion!
Making this game was a neat learning experience, and it's a shame I hadn't thought about it during its development, 'cause your suggestion is a great quality-of-life improvement. Unfortunately, I don't plan to update the game anymore. Had it come to mind then, I would have been glad to try and make the controls a little more intuitive, given that it shouldn't have been too difficult to change it up -- and honestly, maybe not even as it stands is now.
I'll have to try and think a little more intuitively in the future. Thanks again, though; I appreciate your insight!
