Heyy, that might be because you ran of money. I made quick fix to let people heal even if they don't have money until i find a better way to explain this.
If you still cant heal, reset the game by pressing "R" and reload the page.
i do but except the number, nothing show me if i do it right or not. i think you should some effect viseul or audia to show if the player click in the good timing or not, like mario & luigi you see ?
