It's challenging to see ahead to know which one I need, I would place the player move to the left side of the screen so I can prepare better. It also seems that sometimes I got platforms and placements of the dots that didn't allow me to make the jump. Meaning, I would jump and in midair had to change between the two sizes and in doing so the physics would get messed up and I would plummet to my death since the gap was too wide. Neat concept though. Just needs a little more polish :)
