Unfortunately I couldn't leave a complete review because I wasn't able to get the second to work. I tried using a controller too, but that also only controlled the red ship. So maybe this is for 2 controller set-up? It seemed pretty solid. There's a boost jump feature and a "hover"/Slow-decent mode, so there are fleshed-out mechanics there. And I'm certain I need the blue ship to help get to the end, so design on the first level is solid, but wasn't able too continue.
