so wholesome you made this with your son! i could totally see this being an educational game. not sure how it fits the theme but pretty neat nonetheless. i think the balance could've been better. either slow down the speed growth factor so little kids can have time to think and type, or slow down the speed and make the questions harder so adults can feel challenged but not rushed. lol i can just imagine the local kids raging to this!
reminds me of this flash game i used to play in school called spell n' stack (can't find any vids :( and flash is dead). in this game you use words as logs to get higher. it gets faster overtime but by the time it's overwhelming you're in the sky or in space and have had access to powerups. there's reward to how far you've gone.
i love typing games and miss their prominence. good to see one submitted in a jam for once ;)
