This game is very aesthetically pleasing to play. The sound effects, the movement of the character, the 2D puzzle. It felt really nice.
There were a couple issues in the puzzle like the bottom right sprite not showing the correct way (it's supposed to be facing left) and then the additional puzzle to the middle left needing to be connected since it wouldn't solve the puzzle without it being connected even though the beginning and end was all connected.
Another confusing aspect was the puzzle never closing out or you not being able to close out of it. It would be nice for the first doorway just to show locked or some sort of icon showing that the puzzle was solved or not.
The monsters being included in the puzzle felt out of place since I think the original idea was to have some sort of circuit feel to the puzzles which would have been enough. Maybe a glowing lit wire glowing as the puzzle was connected in the right order to tell the player they were connecting a wire/circuit even throughout the dungeon as you walked to the exit along the floor.
Otherwise everything else felt really nice. I really adore these kinds of puzzle games where you have to connect stuff together to solve the overall puzzle. It's a unique take on it with the dungeon feel to it. If the dungeon part could feel more organic or have obstacles, I think this game would really take off. Great work!!
