Super charming! Loved it. Took me about 20 minutes.
Is it possible that the 2nd room with a collectible/trinket doesn't restart properly? I think I got stuck there on my 1st attempt at getting the trinket, since I got the battery in a position where I couldn't grab it back, and thus I couldn't get to the next room. Well, I started the game from scratch and got there quickly the 2nd time around, so no harm done. Got the darn trinkets eventually!
Thanks for playing! Took me more than a day!
And you're correct. Rooms with collectibles have been set to be persistent in order to remove the possibility of collecting the same piece multiple times. This affects all objects, hence why the blocks don't go back to their original positions. I didn't realize the battery could be moved into a no-return position, though! Most decisions were made in the spur of the moment, hence various issues.
Fun that you retried and succeeded in round two!
Ah I just about suspected it was the same in all trinket rooms, I just didn't get stuck in any of the others so I didn't want to assume. Well now I know my lost time was for a good cause—saving you the hassle of implementing object-specific persistence. A sacrifice I'm more than happy to make for a fine game like this.
