Submitting this game to a dyslexic stream is evil - that said, you requested feedback on the concept and game play features!
I think The core idea fits, however I think a little more clarification on what the tasks will entail (especially when mistakes ADD stress) would be an immediate boon - However given you have effectively made 5 games in 1 jam makes fitting any level of polish really difficult!
I think this nails the feeling of stress tho - especially given the misery and length of the sentences you are requested to type, combined with how little the minigames relax you and deminish over time, demanding you earn more money is really clever. Especially for me, who can't spell. you bastards ♥
