Pretty fun! I had some issues with the UI, like the button for scrolling the inventory having such a small hitbox I almost thought it just didn't work and that I was softlocked, and needing the mouse wheel for dialogue options is not ideal (mine is broken, and I need to do hacky stuff for things like that, buttons would be appreciated).
I also thought it was sort of annoying that holding an item makes you unable to leave the fusebox ui, and that clicking an item in your inventory while already holding it doesn't put it back like you might expect, but causes the character to say the generic "doesn't mix" line.
Also, some of the interactable objects really should be more visible. The toy lever in the first room specifically was tough to spot, I was clicking around in there for a few minutes. The flower-shaped metal piece also was pretty hidden, though I did fortunately find it when I needed it really quick, but I think I was just lucky, I could see others struggling on that for a while.
But all that said, I enjoyed this! It was pretty charming, especially with all the voice lines being properly recorded and not text on the screen like is often the case. Really brings you back to old flash game point-and-clicks.
