I think you implemented the theme and special object quite well on this one. The idea is simple but it makes for a fun gameplay loop, and I like how the whistle sounds on this one. For the timer, I'm not sure how you were planning to implement that one but at least on my end, I think the issue is that I couldn't see where the timer is so I wasn't sure if I was going too slow or if I was on the right pace. But overall, this was still a fun game, and I enjoyed reaching the end!
