All the stars.
I used to write little web games for my kids during the pandemic and they were 1st graders at the time.
Dunno if I made a "which number is greater" game or not, but I did make some addition and subtraction ones. Mine were straight html5 using buttons.
I notice a small glitch on the room with the exit to the left, where I could go through the block above the exit and go off into infinity. Prolly a hitbox thing.
Anyway, delightful little game and suitable for its intended audience.
All game should have burping sounds.
