Hey Mika,
You know when you said "I didn't want the theme to turn my game terrible"? Yeah, that's where you and I should have a beer together. A lot of that in this jam. And your game is enjoyable because you didn't decide to make clicking on letter A activate the Space key, because the game is a liar, trololol.
With that said, the rating system is there and I have to use it as it was designed. So it scores low on theme. My own game also has the theme expressed in an unintrusive way. The premise is our protagonist, Hank, wants to demonstrate the Earth is not a 3D spheroid by digging down. His reasoning is, "if I can't get to the other side, then it cannot be a sphere". What a shame that the game is endless, so he will never find an answer either way. So the game lies to him. Most people who evaluated the game can't know this, so they marked it as not matching the theme. No fault of theirs really, but the philosophy for me is: games are supposed to be fun and enjoyable. No theme is going to get in the way of that.
Also, all jams don't have a rating for Function / Polish / Execution. So, I could give somebody a 5 star in Game Design, but their game crashes 100% repro rate on level 2. There is no rating for "my game actually works". Your game would score 5 on this category, which doesn't exist... yet, it's all important.
Also, all hail programmer art! May it live forever.
Cheers.
