Hi, I've made a video about the game and thought that you might be interested in getting some feeback about the game + the footage of my session. I hope this helps ^^
Footage:
-The gameplay mechanics, the playable loop and the concept itself it's reaaaaally good and original. I loved it, it's a quite interesting way to aproach creating and solving puzzles overall + the way the story appears in game it's interesting too ^^. I think the game has a lot of potential in general.
-I found some bugs that you might want to check out on the video, literaly it felt like I managed to broke the "toy" hahahaha.
-The visuals are really on point and combined with the mechanics make the game feel like actually playing with a toy and it feels pretty cool :D.
-Adding some visual clues like making the icons on the partiture glow in the first few levels to make the player instantly catch how the puzzles work could help without needing to implement an intrusive tutorial.
In general I really loved the game.
Hopefully this is useful to you :D, also if you could subscribe that would help me a lot :)
Regards
