Today I spent most of the time fixing errors. It’s now ready to be played and I will ship it shortly.

• The answer was always rounded to the nearest integer, so it kept displaying a 0 when that’s physically impossible (it was supposed to display a decimal value 0~1). I fixed it by changing the casting error. Now it correctly rounds to the nearest 10^-6.
• I slightly modified the introduction to reword any unclear details.
• LetsCheck wasn’t functioning correctly, and I had no idea how to fix the implementation. I consulted AI to fix it, because I tried to come up with an idea (using a complex parsing method) for around half an hour and that ultimately didn’t work.

I have to admit, this game is very challenging. I plan to introduce a difficulty setting, in a later version.
