No, It might be youre computer, I did all development and playtesting on a 13" macbook air so it should be fine on a laptop! Thanks for trying to play!
I'm having the same issue. The "hold ctr or md and scroll to zoom" doesn't seem to be compatible with trackpads, at least not on Windows. If I use my browser's zoom function to zoom out a bunch, it becomes somewhat playable for a while, but the camera system gets super wonky as the level goes on, scrolling to show only the top or bottom half a room at a time, for example.
