Ya, you're right. I know this type of game isn't really a good fit for an event like this. But influence of Undertale, I've always wanted to create a game with a complete story, quite challenges, lots of fun moments, and plenty of little secrets to discover.
And the math bug, I actually planned to force the player back to the center after answering the question... but I completely forgot to implement it XD.
Thank you for your feedback! I'll take these lessons to heart and keep learning and improving!!
