I think it would have been great if the frequency in which the ghosts appear got greater as time progressed, but otherwise this is a fun little game that I played for probably longer than I should have!
Thanks! I originally planned for scaling difficulty over time, and hoped if I could find time to add them, to have a few different ghost types and towers, but productivity is fickle.
I'm glad you enjoyed my little project, I had fun making it!
