Due to COVID-19 and family issues there has been a considerable limited amount of flying. Flying practice flights to regain proficiency in all aspects.Assigned a heading and altitude of 2;500 feet on departure from ZZZ. If given a change to ATC I missed the call; but do not remember hearing it. I climbed to 4;500 feet which was my flight altitude.I was told by Tower to go to Departure. Departure stated I climbed to an unauthorized altitude as there was possible traffic. Was not allowed above 2;500 feet.Miss-communication and getting back into the system after the layoff. This is why I am practicing in VFR conditions with various phases of flight.
GA pilot reported an altitude deviation during departure and cited lack of flying as a contributing factor.
