I really enjoyed this. It reminded me of a game I used to play a long time ago. I really like the puzzle aspect and would love to see this one expanded. One nitpick, I never play with arrow keys, so that was a bit jarring, but I did finish!
Thank you for playing and for the feedback! Indeed, if I had programmed A and D as alternative controls, it would have covered a wider range of control preferences, making it more comfortable for more player profiles. Thanks, I'll pay more attention to that!
