Tried to play your game, but failed miserably at level 2 after many attempts.
From what I can say based on first level, "wraparound platformer" idea is in principle interesting, but thematically at odds with both electrician / lightbulb theme and wooden background. Maybe something space-related or magic-related can fit better.
Also, 'falling through' the bottom seems to be implemented by resetting the whole screen and character position to default, which is both visually jarring and defeats the point, since there is not reason now to aim when jumping down.
