Sorry for the delayed reply.
Thank you for the wonderful feedback.
This might sound like an excuse, but I do feel that with more time, I could have done more. Since I'm developing this alone, I don't think I was able to do enough playtesting or other preparations.
However, releasing the game has allowed me to receive a lot of feedback and gain perspectives beyond my own.
As a quick fix, I've updated the game page for new players.
