Congrats on almost getting 200 ratings on your game! I also noticed it was quickly climbing to the very top of the most rated. That's a huge achievement. For your 2nd game jam, top 6% is AMAZING and a huge improvement from 30%, so you should be very proud! Most games don't make it that high, and most games don't even make it to 50 ratings. With about 1500 games, its nearly impossible to make it into the top 10 in any category, so don't feel bad.
Most jam submissions don't have that kind of customization, and options are usually nonexistent or very minimal, so that might be why people didn't check. Also, most people might just look in the page description for the controls before playing. That could also be why. I guess you could just take that critique as non-applicable. I personally didn't have any issue with the controls and thought your game was overall pretty good! Although my point still stands about improving the story, if you do end up going back to the game!
Also, how many games did you rate? It seemed like every game I went to rate, you had already rated it, lol. I always saw that you had commented just a few minutes or a few hours before I managed to leave my rating and comment on that same game.
