I'd just like to retract my earlier comment concerning an Impossible badge. It's just one of those hard ones that relies on some chance as well as ability.
If I could make one change, it would be to have the regular mouse cursor on both sides.
It's a little bothersome wondering if there's a slight difference that I just can't see because the circle and pointer are making my brain automatically class the minor discrepancy as an optical illusion.
Yep. Definitely broken.
Tried stage 3 again.
Managed to spam the left and right keys enough to get to the part where you press the space bar before even the first of the horde reached the steps. Pressed the space bar. Pressed the space bar repeatedly. Held down the space bar. As you can see by this comment, my space bar works just fine.
