Quick Math Alright, I really like the concept and think this game has a lot of potential.
Here are some things that could make the game better:
1. When you writer your answer, you have to click on the button "enter", but I think you should also add an option to just press enter on your keyboard, it's much easier to play that way
2. Change the music that plays during levels to something more chill/mellow, techno doesn't really fit with the gameplay and it's a bit distracting
3. Improve the quality of the pictures/backgrounds and change the font a bit so it looks cleaner
Other than that, it was pretty fun. Hope you continue working on this game and make more games in the future!
