Unpack

FirstLoveExperience folder. Then unpack
FirstLoveExperience_hashes.zip (attachment to this post) into
FirstLoveExperience folder. Then run
chk.exe from
FirstLoveExperience folder, click menu "File" -> "Load list" and point it to
FirstLoveExperience.sha256. It will calculate hashes of all files inside the game folder, checking it against known good values.
You will get next screen:
Click on "Name" , I marked it with red line. This will sort files differently and put files that didn't passed integrity check on top like this:
Ideally you should not have yellow exclamation marks at all, only green 'okay' marks. Two dublicate files, 01.png and other one are okay. At this example I intentionally modified FLE.exe and check tool shows it with yellow exclamation mark.
If you will get yellow exclamation marks, redownload and reextract game archive and check again. If files are okay, then there is something wrong with the game internally. Masobu (the game dev/publisher) usually doesn't test their games well enough so they often don't work properly on some PC/OS/OS Settings combinations.
