Played your newest level. Great idea, with equal execution. Needed quite some tries though, because I was stumped a couple times wasting too much time. Don't know if I did the rooftop part correctly though. It kind of looks like you need Yoshi, but as far as I'm aware it's impossible to get him up there so I let myself take damage while throwing the trampoline forward and using the post-hit invincibility to reach it in time and jumped to the tower. Well, it worked .
