Yes but you go from an easy one direction two levels later, you have ships with shields and you have two directions to worry about.  I am dying on 4th level, and if that is the case, I will never be able to do a few steps up.  Which is exactly what the issue with some games are, they don't ease you into it,. they just slam you in and you lose over and over again till you finally find your way.   I don't enjoy those sorts of game but then again, I am not your typical gamer at 65

@honkwomp3 Do you think it would make it easier if they had a feature that caused the entrance point for a wave to highlight when you're hovering a cursor over a future wave and maybe a snap-to-location if the wave was clicked on?

Adding the potential routes of ground-based units when control is pressed down in addition to the routes of flying units.  The different routes could be color coded according to the direction they're coming from.
