you should try using a higher distance snap multiplier. 1.1x would be a good choice, 1x creates barely touching overlaps that do not look very nice, especially at this bpm.
spacing was also very inconsistent within the map. places like 00:25:471 (3,4,1) - shows spacing emphasis on (4) instead of the new combo. when i map my easy difficulties, distance snap is enabled the entire time. this ensures that there are no issues with spacing. go into AiMod with Ctrl + Shift + A and toggle "Check distance snap". make sure your multiplier is at 1.0x. it shows you the inconsistencies found in your spacing (https://puu.sh/EJ8KU/4a065e86fa.png).
this difficulty also appears particularly rushed compared to the other ones. old slider design 00:16:556 (1) -, combos 00:38:156 (1) -, and rhythm issues 00:19:299 (1) - is found in the map. i also do not agree with many of the rhythms used here. even if its only the easy difficulty, always remember to go back and check your map for errors. AiMod cannot catch everything, such as snapping to an incorrect tick. play through the map to ensure that it is playable and flows perfectly. i recommend taking a look at easy difficulties of other maps with around the same bpm and to using similar rhythm choice and spacing. good luck <<<
if by "stack this onto the (1)" you mean stack 01:28:186 (4) - on 01:27:849 (1) - then i think its too spaced. if you could clarify that would be great
