You can press A to blow up all penguins You can press ESC to end a level immediately You can press F or SPACE to speed up time You can press P to pause/unpause the time You can press S to pause time (kind of useless compared to P) You can speed up time in the map navigation screen making the penguin move faster ( :O ) You can advance through menus by speeding up time (instead of presssing the checkbox)
So Cuttyflame just beat my time with one full second using the same routes as me (except level 12 which only saved about 0.3 seconds) i had a hard time to understand how this could be 1 second faster in total, im guessing it's because of loading times between levels or potentially mistimed run. So my suggestion is to instead of using RTA use ingame time by adding up all of the times you can see at the level selection screen.
Following this method my 2:35:56 run would be a 2:14:65 IGT and Cuttyflame's 2:34:52 run would be a 2:14:58 IGT which to me seems alot more accurate.
This would eliminate any timing errors or inconsistent load times, also it would make it easier for mods to time the runs as it only requires adding up the times at the end instead of timing the video frame by frame. Only problem is this only works if the run is deathless so this might not work for any% but in my opinion it should be used in 30exit and the other shorter categories where deathless is possible.
A new rule would be required to show all the level times in the level selection screen at the end of the run. (which both me and Cuttyflame are already doing in our runs)
