After clearing world number three, the achievement didn't unlock. After the game crashed it was impossible to go into the options menu. After another restart, that worked again, but the game crashed with an error after clicking on 'Adventure'. Please don't ever bind the menu to 'right click', this is what crashed the game for me and it is horrible design....

Kann man irgdnwie auf die optionen kommen? Er startet direkt immer das game!
