And here's a movie that reaches the score of 22 60 frames sooner: User movie #638128340520305920
Turns out dependency between coin grab and next coin spawn is non-linear, and sometimes it's more optimal to grab it later, and the next one spawns sooner. Hard to tell how this affects the whole movie, but having to test a few more of the same button presses for every coin sounds easy, just a bit time consuming.
If we blindly
extrapolate this to the whole movie duration we get 00:20.80
seconds of potential improvement, and for the overall required score we get 00:45.40
Of course it's impossible to know if in practice actual time saved will be more or less that that. But what we know for sure is you can't just fall on every coin ASAP and be sure the next one spawns optimally. There's a bit more room for manipulation. And in a game as basic as this (you just move left and right), it's fair to expect a bit more attention to details.
Also since you can manipulate the coin's X position and you have 9 lives, it would be worth checking if you can manipulate the last few coins to align so you could collect them without input while losing all the lives.
In theory it should also be possible to manipulate coin spawns a few coins ahead if it takes too long even after all the tries on the immediately previous one. But that makes it a much bigger project.
