I had fun playing this game for a while, at least until I found that certain things seemed a bit odd, such as:
- the 'Next Level; button doesn't seem to work despite clicking on it using my mouse several times;
- I can't access the 'Student Wizard' level; and
- from Graduate Wizard up until Supreme Wizard, the 'Too High' and 'Too Low' texts seem to be buggy, as no matter how high or low I go, I can't get the correct number at all, even when I key in 0 and the the 'Too High' text still shows up (unless you're supposed to click the 'Guess' button using the mouse instead of the Enter key) :(

It seems to be useful for kids to pass the time while teaching them logic, so please keep working on it :)

Note: I was playing this game using the FireFox browser in the Incognito mode, so that might have interfered with the game's settings/coding :o

Seems like an interesting way to teach binary search! And yeah, can totally see this on mobile! Well done! :)

I really liked this game! The sounds and the art were really nice and gives the game a nice charm to it, and the game itself was a lot of fun to play.

Since you are planning to release the game on mobile, here are some suggestions that I feel may help you improve the game:

- Sound effects for each kind of guess, one for too high and one for too low, with perhaps a visual of some sort (such as a flash, or even better, animations of the wizard signaling with his hand and body language).

- A non-plain background

- When I press "Enter", I lose a life but the guess indicator doesn't show until I press the "Guess" button. You should handle both cases as some people may find it more convenient to press the "Enter" button to submit a value from a text field.

On a side note the apprentice wizard has only 11 possible numbers and you give the player 10 guesses which is far too many.

Congrats for finishing the game! I liked the wizard and how it almost looks like he is going to flash the player, but it instead just explodes in numbers. Note - if you press enter after typing in the number, it just disregards the number that you type and doesn't give you any higher/lower feedback. I almost won the final level but pressed enter and lost that final guess.

A few more different types of maths problems could see this becoming a great brain trainingish game, though not sure I'd be happy leaving a kid in the care of the creepy old flashing Wizard (though thankfully he's fully clothed underneath)

One bug though, the second level, Student Wizard, doesn't seem to work. Both the main menu button and the 'Next Level' button on Apprentice Wizard don't work. Checked the console and got this error:

Scene 'Level2' couldn't be loaded because it has not been added to the build settings or the AssetBundle has not been loaded.

This would be a nice tool for math teachers who are introducing their students to statistics; it's also helpful for doing division in your head and keeping a running tab, so I could totally see this being at home in something akin to Brain Age. Not my cup of tea, but you did a great job with the logic! I did find one bug I'd like to report, too: when I was on the lowest introductory level and passed it, the option to proceed to the next level of difficulty wouldn't register when clicked. 

Keep up the great work! Cheers!
