Think Fast: Student Reviews and thoughts

Honestly this is the first game I’ve ever created that has any value educationally. All other games that I’ve done before are just simplistic fun to while away your time.
I hope to go into this form of game design that are fun and at the same time educational. The idea of this game came to me when I was just playing with a good friend of mine at a chocolate shop. We challenged each other to get the correct total sum of the prices of two different bags of chocolates within 5 seconds.

I came out champs of course. Hahaha. (After I let her play the game, she turned out to be better than me actually. Felt so silly being beaten after that :/ )
Anyway, I let some of my students in school tried out the game and here’s what they have to say collectively:
*note: These are unedited 
A good place for training mental calculation, building up maths skills for expansion, even during sec 2 and 3s. But it’d even be better if other maths combination are added into it. – Lim Si Ying
 Test your mind, challenging, this game is good but a little boring -Darren Long
Fun and challenging – Jonathan Wee
Nice, quite creative – Yusuff
Think Fast is fun and challenging, good for maths – Anon
A bit easy; hard levels give more time - Anon
Questions can be harder and more confusing - Anon

Yup those are their thoughts. I will be coming up with an updated version to improve on the answer choices so that it will force players to really calculate mentally in their head in order to win.
