I BEAT THE GAME
not sure if many people did, but i beat the game!
Here's my constructive criticism:
The artstyle is incoherent, probably because you took assets from many different places
The fade out transitions take a wayyy to long to happen (like 8 seconds)
Telling the player about arrow controls in the start is good
The beggining weird lever tutorial is good
the house is wayyy too big for the little shadow guy and the game forces you to look at lore which is not good
The piano puzzle is (pardon my french) NONSENSE, sometimes keys dont respond, sometimes they do, the wrong buzzer sound is annoying, and i only solved it because i had nothing else to do, if i DID have something to do, i'd have stopped playing
the 3rd segment is another lever puzzle, but there's a reflection of the shadow guy, which was kinda cool
the background makes even less sense in this level and when you get the key instead of a giant portal opening in the door frame or a giant door appearing a smaller door appears which is REALLY funny
the song is kinda weird and doesnt fit with the game
and i dont really get the lore, there's a pianist and shadow man and shadow of past or something i don't know...
You don't NEED to go with the theme "flow" but still it doesn't fit much
Noticed you use Gdevelop for every game of yours, and you don't need to do this if you don't want to, but if you really like game developing (you've been making games for a year!), i'd change to another engine, try GameMaker or Unity or Godot, just try something that makes you need to script (even if it's visual) to make what you want, i know it's harder than Gdevelop but making a working game in one of those is 1000000x more satisfying
Overall its a decent experience
