In addition to what others said, here's my #1 thought. It gets harder way too slowly. It felt like I was replaying the same level many times in a row, rather than advancing to more difficult levels. Also, a level becomes exponentially harder the more time you wait before getting started. So wasting 2 seconds at the beginning is going to cost a LOT more than chilling for 2 seconds near the end.
