Nice job - it's a similar mechanic to a game I created many years ago where you steer Aladdin on a carpet up and down to the right "lane" for the correct answer when learning multiplication tables while dodging incoming rocks.

https://mordenstar.com/projects/mathemagic

Small bit of feedback: Recommend hiding the little robot or moving him off the physical lanes, I could that being a distraction for a child trying to focus on answering the questions

redcat99•11h ago
Fair point on the robot - I'll try moving him properly off-road and keeping him still while a question is live. Thanks for actually playing it.

It's very strange that the stars appear before the numbers and then they move.

Why the up key send me to the middle lane?

[Perhaps I'm too old] but I think the game is too slow. Is it possible to start with a faster speed and then slow down in case the kid does not pick the correct solution?

> [Perhaps I'm too old] but I think the game is too slow. Is it possible to start with a faster speed and then slow down in case the kid does not pick the correct solution?

On speed: it defaults to the slowest setting because the target player is 6 and still doing finger-counting mid-drive :) There's a "Grown-ups" section on the menu with a car speed setting (Relaxed/Steady/Normal).

Starting fast and easing off on mistakes is a nice idea; difficulty already adapts that way, so speed could too.

gus_massa•6m ago
I got to the biggest/smallest section. It's weird that the instructions appear at the bottom and the numbers at the top. I had to switch my vision to read it.

Are you planing to add localization? [Hi from Argentina!]
