Right and wrong: Equipment, cost and time management

Equipment/cost:
- Computer and processing.
- No cost.
Time management:
- Gathering images 1 hour.
- Gathering sounds 1 hour.
- Adding images and buttons that work in succession with each other to processing 1.5 weeks.
- Adding sounds to processing 1 week
- With my limited knowledge of processing, length of time to accomplish goals within the estimated might be elongated.
