I think this game is really well done! The art and audio are incredible and really set up such a strong tone for the game. You've absolutely nailed the game's presentation, and I love the vibe that it has
I also think this game is probably the most directly related to the theme that I've seen, so kudos for that!
Additionally, I think that the symbol drawing system is executed flawlessly. It never felt unresponsive in any way and I always was able to tell exactly what I was doing.
I do think that the ability to look at your symbols while drawing could have been beneficial, as there are quite a lot to look through which can make remembering them a little harder, but it only would save a few clicks back and forth so it's not a big deal.
I also really appreciate how much you attempt to aid the player, like in telling us exactly how many symbols are wrong rather than staying silent or punishing the player for incorrect choices. In a puzzle game like this, that quick feedback is incredibly useful in keeping players engaged and having fun
However, I will say that some of the riddles did end up feeling a little obtuse. It could just be me, but there were some that I really couldn't figure out well since there was such a wide breadth of answers to pick from where it seemed like multiple could fit. I know that puzzle games are really hard to tune difficulty for, especially when it comes to things like riddles, and you really did succeed with the difficulty on most of them, but I just feel that some ended up a lot harder than others
But overall, I really liked this game! You did a great job with it!
