Firstly, I'd like to say that I really enjoyed playing your game. It's a pleasant, rather light hearted experience with an abundance of generally well defined characters who appear to have their own lives outside the MC and a mystery I'm looking forward to explore. Plus the backgrounds are quite nice and contrast rather well with the colourfulness of the characters.
Secondly, I've got to compain a bit. You could desperately use an editor - the numerous grammatical errors, awkward phrasings and unnatural repetitions of nicknames (like "child" or "big guy") ruin the experience quite a lot. Also, certain events are a bit too silly and cliché for my liking - the phone calls that happen at just the right times or the MC leaving his phone on the table at that one party come to mind. Additionally, 90% of the characters have identical or nearly-identical bodybuilder-esque body types which makes this visual aspect of the game appear rather lazy and uninspired and it caters to just one particular target group, while those who prefer different body types (like lean, fat, musclegut etc.) or to have a variety of choice in that aspect are left with nothing.
Still, all in all, good job so far.
