Ah, you're right. I just tried it non-fullscreen and it seemed a bit easier to control. (Or maybe I'm just getting used to the controls now? haha)
In the first level, there were a couple places where I fell thru the wall and into the abyss. 😅
Am I supposed to be able to go upstairs? It looks like something is up there but I wasn't able to get past the toys.
Then, it said level 1 was clear, although It didn't say that right after I fixed the sparks - there was a pretty long delay.
I didn't encounter any problems with level 2 except I wasn't able to jump over the gap to reach the 2nd outlet. I only tried a couple times, though.
