Fill in the gap

This is my project in Unity so the game is not upto the mark but I've learned alot while making this. I faced many bugs and I've tried my best to solve all of them. Still the game could be much more improved and more levels could be added (I was only able to make two levels due to busy schedule and also couldn't find bangla alphabets). Thank you US Embassy Dhaka and Arduino Community Bangladesh (ACB) for such an insightful course.
