ILs are useless because the game is cycle based, also the game is too short for them to actually matter. A better way to try and get the limit of all the levels is to try and TAS the game to be perfect in each one, because it would get reasonable cycles. If you did ILs for every level and added up the times it would be something like 50 seconds because the cycles are different for each run. so TAS is basically the only way to get a view of the perfect run
